Hey guys, today, I have brought the best nutrients for growing cannabis. Now, no matter which levels of indoor grower you are, you are surely going to need the right nutrients for your plants.
I know many of you might not have the right knowledge in this department, but I have an expert team who knows everything. So, I am here to share the proper expertise with you and guide you through.
Now, so many different types of cannabis nutrients are being made for a decent growth of plants, but the question arises which one to choose and what to see in the nutrients before buying it for your cannabis plants.
As plants need different intensities of light during various growth stages, they need multiple soil nutrients for each stage.
If you are a newbie, I am sure you are feeling confused right now!
No need to worry. I am here with the complete info of this scene, and you will indeed not feel the need to catch up on knowledge from anywhere else. This one is a comprehensive review.
Here we reveal the review!
Best Nutrients For Growing Cannabis Reviews in 2024
Contents
Now there are certain things which you must know before coming to the actual topic. No matter which nutrient bottle you buy, you will see three numbers indicated on them: NPK/Nitrogen, Phosphorus, and Potassium. Now you will see the digits there.
For example, if your bottle has 4-3-2 written on it, then 4 stands for Nitrogen, 3 stands for Phosphorus, and similarly, 2 is for Potassium. These numbers vary right from 1 to 15 max.
Now, the ratio must be right for fulfilling the requirements of your cannabis plants. We are going to read that in the next paragraph!
The perfect ratio of NPK
Large-scale testing is illegal. As a result, no one has got the “best ratio” for growing weed plants. Here I am going to show the ratio, which has worked the best. It depends upon the conditions.
The amount of calcium present in water always affects the balance. So, the ratio depends upon where you are living, as the water supply is different everywhere.
It means if you live in Texas, the calcium percentage will be different in water compared to your uncle living in New York, right? Now how to figure out what ratio is the best at which place? You need to keep a grow journal or follow a senior grower. Here I have classified appropriate NPK levels for both the growth stages that have worked the best.
Veg stage:
- High Nitrogen level.
- Medium Phosphorus level.
- High Potassium level.
Flowering Stage:
- Low Nitrogen level.
- Medium-high Phosphorus level.
- High Potassium level.
Furthermore, when your plants are going through the veg stage, you can use general-purpose cannabis plant nutrient because nitrogen levels are high in them, and nitrogen is what your plants needs during that era.
The scene is a bit different during the bloom stage. You require a higher amount of Potassium and Phosphorus in comparison to nitrogen.
Now, if you are thinking of using a general-purpose cannabis plant nutrient the way you used it during the veg stage, then beware! That will heavily affect the cannabis plants’ growth, and later on, the results will not be what you were expecting.
Here we are using higher potassium and phosphorus levels because they make flowers bulkier, the same way pizza makes you! If you are getting greedy for bigger and heavier flowers and using extra-high quantities of phosphorus and potassium, then again, beware! That will also severely harm the plants.
What about organic nutrients?
It is a significant factor of confusion nowadays. Are organic nutrients right for cannabis plants? If yes, then how much? It might indeed increase your buds’ aroma, but I will not recommend you to use organic nutrients in a hydroponic setup. These can lead to the growth of bacteria when they come in contact with water.
Chemical nutrients do a better job when it comes to Hydroponic setup. They also support your plants and help them in growing quickly, and no bacteria issue there.
Nutrients suitable for hydroponic setup
Many indoor growers grow with mineral nutrients. but the soil isn’t involved in hydroponic. The standard method is to fill buckets with water and nutrients, which your plant. can soak up a significant percentage of nutrients for hydroponic purposes only.

Frequently Asked Question
What is the ideal time to start feeding my plants with nutrients?
During the growth season, feeding is usually done in the spring or summer. Even if they are winter-flowering, few plants require fertilizer throughout the winter months.
You may give your seedlings their first nutrition feeding once they have produced 3-4 sets of genuine leaves. It usually takes 3-4 weeks for your seedling to use up all of the energy left in the seed once it has germinated.
Is it good to use nutrients every time I water?
Use liquid nutrients every other watering, or two waterings on, one-off, rather than every time you water. It all relies on how complicated your soil is and how healthy your plants are. Overfeeding with nutrients may harm your plants. Giving weed plants the correct quantity of nutrients necessitates close attention.
When should I stop giving my plant nutrients?
You may cease feeding any fertilizers in the last 1.5–2 weeks of blooming to avoid harsh flavours and unsavoury chemicals making their way into your stockpile. If you’re growing hydroponically, don’t stop feeding until the last five days because they’ll be growing only in water.
How often should I feed my plants with nutrients?
Once a week, fertilize your houseplants. Feed your garden plants every two to three weeks. However, fertilizing your landscaping plants once a month is sufficient.
Can I create my nutrient system?
It’s both enjoyable and helpful to make your nutrition. Your plants don’t care from where they acquire their nutrients, as indicated at the start. Instead, they will be content and grow to their most significant potential as long as they have all they require.
What is the ideal balance or ratios between the nutrients for cannabis?
In general, NPK ratios of 3:1:1 are ideal for any cannabis strain at any stage of development. Nitrogen percentages should be reduced when potassium and phosphorus levels rise after the plants begin to blossom. A 1:3:2 ratio is required for early blooming; a 0:3:3 ratio is required for late flowering.
Wouldn’t you see toxicities on cannabis anyway if you feed too much?
It’s too late to fix the problem if you wait for toxicity symptoms to occur on cannabis. Cannabis may sit tight and not grow due to hazardous nutrient levels even before signs of toxicity appear.
What nutrients does cannabis need in the vegetative stage?
Nutrients. Nitrogen (N), Phosphorus (P), and Potassium (K) are the three most essential nutrients for the Cannabis plant to grow (K). During vegetative development, N is critical, with lower amounts of P and K.
To allow them to grow 2-3 feet tall, your plants will also require an increase in warm water, a flow of moist air, and a lot of soil space at this stage. Cannabis plants, like seedlings, should be grown in well-drained soil throughout vegetative development.
Can you use regular soil to grow cannabis?
Peat moss-rich soils are an excellent alternative since they keep the soil wet. Nutrients. If you’re growing cannabis, you’re almost certainly fertilizing your soil using a nutrient-based fertilizer. That implies you only need high-quality, general-purpose soil in terms of nutrients.
How does phosphorus affect plant growth?
Phosphorus is required for flowering in cannabis. However, more phosphorus does not result in more blooms. When you supply more phosphate and potassium while nitrogen is scarce, cannabis sees the situation as a nitrogen deficiency and slows down its development to compensate.
