How big should buds be at 5 weeks? – Harvesting Guide

We all have our concerns at every stage of plant growth. If you are concerned about How big buds should be at 5 weeks into the flowering stage, then get dwelled in the article. There is much more to learn!

You might be curious about the precise size of the buds at different phases of the growth cycle if you produce your marijuana. So, at five weeks, how big should the buds be?

Here, you must remember that we are discussing the first five weeks of the flowering stage, not the first five weeks of the growth cycle. The vegetative state comes first, although this is irrelevant because buds cannot develop at this stage.

Growing weed plants is fun, though hard many times. Plant growth is affected due to climate, location, and many other parameters.

But, there are a few standards that decide healthy growing plants. Here we are discussing those.

So, stay with the article till the end.

There are many tips and surprises between the lines, and certainly not to miss!

How big should buds be at 5 weeks into the Flowering stage?


Week 5 is crucial and decides how your crop will be in the future. So it is important to know every detail related to week 5.

So, we don’t directly jump to week 5. Instead, I will tell you how your bud should look at each stage.

First, look at the general adaptation of the bud at 5th week of their growth.

General Concept:

Generally speaking, those buds should be between one and three inches long and one-half and one inch wide at five weeks into the flowering period.

However, this is particularly true for the colas, also known as the crown buds on top of the plant. Further, the type of strain, quality of seed, temperature, and many more parameters must affect the bud’s growth.

Let us learn about the whole growth cycle of buds growing in their flowering stage.

Week-by-week study of cannabis plants in their flowering stage:

Week 1: The transition phase of the flowering plants

How big should buds be at 5 weeks

Your cannabis plants will be in the transition phase throughout the first few weeks of flowering. Your plant will probably grow quickly since she will be anticipating the impending winter and the heavy load of buds she will soon have to carry.

Some strains during this time can virtually double in height. The stretch phase is another name for this early flowering stage because of how quickly your plant grows.

Growing “green stuff” like leaves and stems is what your cannabis plant is doing to get bigger, stronger, and more resilient.

Plants stretch and increase in growth and height starting in weeks 1-3. However, as plants experiment with significant alterations, this stage is also referred to as the transitional stage. As a result, plants expand and sometimes quadruple their leaves and size. Your plant will develop several new leaves, usually near the top of the major colas, even as it works very hard to grow in size and height.

The stretch phase is another name for this early flowering stage because of how quickly your plant grows.

Things to be taken care of during week 1:

Growers must take care-

  • Your plant will now require more growing nutrients even though it has formally entered the flowering stage.
  • Flowering Nutrients schedules shouldn’t be abruptly changed, and you shouldn’t switch to blooming nutrients overnight.
  • Remember, those nutrient deficiencies may lead to complexities in the flowering phase.
  • Once flowering begins, it is typically advised to feed plants more growing nutrients for at least another week.
  • For those considering applying low-stress training (LST) methods due to the stretching of cannabis during early flowering, this is the time.

Week 2:

Week 2 Female

You may notice the first white pistils forming on your female cannabis plants during the second week of the flowering cycle.

It happens where the large fan leaves meet the main stem, where these tiny, wispy white hairs will grow. These little hairs are what will eventually develop into buds. Only female plants will have these white hairs.

On the other hand, if you are growing male plants, your cannabis plant won’t develop these “hairs.” instead, it will develop tiny pollen sacs.

Growers determine the “sex” of your plants at this point.

To distinguish the males from the females if you are growing regular, non-feminized plants if you are unsure of their gender.

Things to be taken care of during week 2:

Any plants producing pollen sacs rather than pistils should be removed because they are male and won’t produce buds. Additionally, they can help your female plants produce seeds by pollinating them.

Thus it is a crucial stage where you understand and separate male and female plants from each other.

Week 3:

week 3 plant

Week 3 is the time when the growth is in full swing. You will notice that your cannabis plants will now be roughly 50% bigger than they were only three weeks ago, and they haven’t completely stopped growing.

While still a little stretched, the stretch is already beginning to settle down and will soon end.

You can now see the first indications of true marijuana buds forming where you could previously see some hairs on the plant. Unfortunately, your plants still won’t have a lot of resin glands and trichomes, so that the aroma won’t be overpowering just yet, either.

The plant begins developing its bud sites in the plant nodes toward the end of the third week. You will notice real buds growing.

Keep an eye out for groups of female preflowers until the next few weeks.

Things to be taken care of during week 3:

  • As you know, the future bud sites are all those locations where white pistils have been growing; there’s a danger that bud won’t grow if you unintentionally clip the preflowers and fan leaves.
  • Perhaps, during this stage, you can softly prune your plant’s leaves, but take care not to touch or harm the budding areas.
  • Before our plants begin to form buds, it’s also crucial to look for pests, mold, and fungi. Most importantly, eliminating them now will likely be simpler than waiting until the plant is in the blossoming stage.
  • It is especially important during this flowering phase, as your plant begins to focus more and more of its energy on developing blooms.
  • It is important to have concerned about verifying the appropriateness of the nutrients you administer and the suggested dosages on the labels. Also, check on the nutrient schedule to maximize yields.
  • As your plants become pickier, you should keep an eye out for any potential inadequacies that could appear in various ways, like discolored, yellowing leaves or a complete lack of leaves.
  • Most growers recommend keeping an eye out for any potential overfeeding that is nutrient burn symptoms that may appear in your plants at this time.
  • Suppose nutrient burn manifests itself as discolored leaf tips. If this occurs, you must reduce your feeding to avoid nutrient burn.

Week 4:

How big should buds be at 5 weeks- week 4 plant

In weeks three and four, the frantic stretching that occurred in the first two weeks will start to calm down, but your cannabis plant will still be growing upward. At this stage, all the ud sites will be white and virtually straight out, and you’ll start to see true buds instead of just milky white hairs, as in week 3.

Your cannabis plants likely stopped growing completely and were concentrating all of their energy on developing buds by week four of the flowering period. White hairs will still protrude from the buds and growing buds, but the buds themselves will get bigger and fatter every day.

Additionally, your plants will create more trichomes as more and larger buds develop, increasing the odor’s intensity as buds start growing at full flowering mode.

This is a kind of resting stage for the growers as you won’t have to focus on training your plants any longer because they will have ceased growing.

Branches that you previously bent down may now be considered being held up if they need structural support.

Things to be taken care of during week 4:

  • In weeks three and four, your plant will become more selective about its surroundings and nutrients. Therefore it’s critical to pay constant attention to your garden. However, since there are still a few weeks left before the end of the flowering stage, you need to ensure that you are growing plants healthy.
  • Further, check for nutrient burn and nutrient deficiency like you were doing in week 3. If leaves of hairs turn darker or yellow, pay immediate attention to your plants.
  • Also, consider lowering the humidity levels at this flowering stage, as growing bugs would easily catch bud rot, and your hard work would end in vain.

Week 5:

How big should buds be at 5 weeks - week 5

Week 5 is all about the full flowering mode. Now learn How big should buds be at 5 weeks?

Your buds are getting fatter, so soon, you’ll have buds that have substance! The pistils will still be almost all white and protrude straight up in all directions, but the buds will become bigger daily.

You may see the thickening of the buds all over your plant during the fifth week of flowering. Additionally, you can notice new buds forming in unusual locations, including along the main cola.

Cannabis plants will gain weight daily due to the abundance of buds. However, if this is the case, you are unmistakably in full blossoming mode.

Further, some white pistil hairs on your cannabis plants may have changed from white to brownish or amber. Don’t worry! It’s completely normal!

At the same time, you might notice portions of your plant’s trichomes become opaque when you inspect them.

Also, your plants are getting close to harvest time when the trichomes turn milky white, and the hairs darken.

Your plant will now emit an extremely potent odor. If you cultivate inside or in an area where it is illegal, ensure your ventilation system is adequate.

Things to be taken care of during week 5:

  • If your plant has grown under the grow lights, you might need to think about super cropping, which involves forcing stems to bend at a 90° angle under tremendous stress. Normally, it would help if you didn’t do this late in the flowering period.
  • Even in these weeks of flowering, the plant should still be predominantly green from top to bottom. However, some lower leaves may turn yellow as the plant focuses its energy on the leaves and buds receiving the most direct light.
  • If you started training your plant a few weeks ago and have noticed some changes, you should still do so.
  • Additionally, keep in mind that your plants are currently devoting all their energy to developing buds, so any stress or damage could impede that process if you need to knot or move your plants at this particular flowering stage.
  • Remember to reposition your grow light or plants as necessary to ensure that they remain at a safe distance. You may find difficulty in adjusting in your grow room.
  • Your plants are now developing quickly and need more energy. Therefore it is important to follow their feeding and watering schedules for the best results.

Week 6-8:

How big should buds be at 5 weeks - plant at 6-8 week

Although different strains possess different flowering cycles, we can say that flowering week 6 is the late stage for many of them.

We can also say that the plant is about to be ready for harvest sooner.

The sixth week of your marijuana plant’s flowering cycle is when various events are likely to occur.

The buds will first get significantly larger. When harvesting, typically between weeks eight and twelve of the flowering period, those buds can often grow between 25% and 35% from week six or week nine.

The plant itself determines how long it takes. For example, when your plant is ready for harvest, which usually occurs between weeks 9 and 12, the buds may measure up to three or four inches long and two inches wide.

Dense trichomes, significant odor, and thicker buds are the signs that your plants are growing well and are in weeks 6-8.

Things to be taken care of during weeks 6-8:

  • All those white hairs should have gone amber by the time your plant is prepared for harvest. This could also be the moment to begin flushing your marijuana plant, depending on how long it will take to mature.
  • In other words, nutrients and fertilizer are not things you want to smoke or consume. Thus, you will start feeding your plant simply water to flush out any remaining amounts in the soil and the plant.
  • Remember that flushing is a very important step before harvesting. It would help if you started doing it in this particular flowering stage.

Remember each step as it is very important for the further vegetative growth of plants.

Depending upon the various strains, some would take 10-12 weeks to step into the vegetative stage.

How to keep your cannabis plant healthy:

  • Use the right method for trimming leaves or removing them. Every 5-7 days, a proper thinning will remove 20–40% of the mid-to-top foliage. By removing these fan leaves, the lower buds receive more light and have greater airflow.
  • Removing fan leaves is a must for gaining quality buds.
  • Don’t forget to remove the discolored leaves during week 5. These can harm plant growth.
  • Grow seeds that have good genetics.
  • It would be best if you took care that your plants are getting enough light cycle, whether indoors or outdoors.
  • Remember to take care of the light cycle, as the uninterrupted darkness of many hours will help your plants enter the flowering stage.
  • Keep watch to avoid nutrient or light burn, and these are enough to damage your crop.
  • If growing buds indoors, try not to grow more than one plant to four.
  • Your buds gain most weight around weeks 4-8. Keep removing those which are unnecessary, like discolored leaves or damaged ones.
  • Watch out for male flowers and keep separating them from females at the start of flowering.

When does the flowering stage begin in cannabis plants:

Flowering while growing outdoors:

Plants growing outside begin their flowering phase when the days get shorter, usually as autumn approaches.

Flowering while growing indoors:

When growing cannabis indoors, the photoperiod needs to be changed to a schedule of 12 hours of light and 12 hours of darkness. You must give a proper dark period to these plants.

Flowering in Autoflowering Strains:

The vegetative stage of autoflowering strains lasts for around 4 weeks before it automatically starts the flowering stage.

They don’t require a photoperiod change to do this. Existing buds and relative humidity

FAQs: How big should bud be at 5 weeks?

How long do the flowering stage last in weed plants?

The length of the flowering phase varies according to the strain.
Depending on the strain, the cannabis plant’s flowering period typically lasts between 8 and 11 weeks. Typically, it is broken down into three weeks or stages. Indica strains often blossom for 8 to 10 weeks. However, this is not a must.
On the other hand, Sativa strains could require 10 to 12 weeks. However, hybrid strains often require 6 to 10 weeks to mature completely.

When to start Flushing?

Flushing should be done two weeks before harvest, depending on the length of flowering for your specific strain.
In these last weeks, when you “flush,” you stop providing fertilizers and only provide the plant with plain, pH-balanced water.
Salts and minerals in the soil will get flushed out) as a result, resulting in a better, purer-tasting bud. If you don’t, your smoke will be exceedingly harsh and possibly taste chemical.

How can I determine the right harvest time for my plants?

To determine the right harvesting time for your plant, you can regularly examine your plant’s trichomes with a jeweler’s loupe or a small microscope.
Further, you can watch to see whether the trichomes change from being clear to milky white. It’s still too early to harvest if the majority of the trichomes you see are clear and transparent. The THC concentration of the buds is at its highest, and the plant is ready for harvest when most trichomes are amber in color and opaque in clarity.

How much should relative humidity be to avoid bud rot to the existing buds?

The major problem of bud rot is that it can completely ruin a harvest. Maintain a humidity of 45% in your grow space to safeguard your plants and maximize their growth.

Conclusion: How big should buds be at 5 weeks?

Indeed. It can appear difficult and complicated to grow weed. However, since cannabis plants are delicate, even a small mistake during the bloom stage can greatly impact the quantity and quality of your harvest.

Due to unforeseen circumstances or because the plant is sick and the buds are starting to look burnt or discolored, you may occasionally need to harvest your plant early.

To achieve the greatest quality possible under the circumstances, it’s frequently preferable to harvest a little earlier if your buds appear finished and you notice leaf symptoms getting worse.

Your buds should thus be considerably larger by the end of week 5, and some white pistols should have begun to turn amber or brown.

You are likely doing something incorrectly if, by every week. However, when your buds are still very small and those hairs are still white, In that case, you should refer to the various sections on tips to keep in mind.

Remember to save this guide ‘How big should buds be, at 5 weeks to the flowering stage, and go through it before turning on your next batch of plants to ensure a wonderful harvest every time!
