Cannabis Nutrients: Best Soil Nutrients for Weed on 2022

Whether you’re a beginner in growing cannabis or you’ve been growing for a long time, you will want to find the best nutrients for your plants. Certain nutrients are made for soil while others are made for hydroponic growing. Make sure you’re selecting the right kind. Also, be aware that giving your plant the right nutrients at each growing stage results in a yield of healthy buds. Each stage has specific nutrient requirements, which can be confusing for beginners. Luckily, we have broken down the nutrient requirements below.
To help you out, here are the seed banks that work in any country.

What is NPK (Best Soil Nutrients)

Before going ahead, it’s important to understand what the labels on the nutrient bottles say.  Almost all nutrient bottles show 3 numbers on them. The numbers come in the order of NPK, or Nitrogen, Phosphorus and Potassium.
If a bottle shows 3-2-4: 3 indicates the level of Nitrogen, 2 indicates the level of Phosphorus and 4 indicates the level of Potassium.
1 is the lowest level of nutrient, while 15 is the highest.

Best NPK ratio for growing cannabis

There is not one best ratio for growing cannabis because large scale testing is not yet legal. However, there is a general ratio that has worked for many that we will show below. Remember that you are growing cannabis in particular conditions, meaning if you’re growing hydroponically the calcium levels in the water can vary depending on where you live. The kind of soil you use, lighting you have, room temperature, all play a factor as well. To get the best nutrient ratio for your particular strain and growing conditions, we recommend keeping a grow journal or asking a grower you admire for theirs.
Generally, the following NPK levels have been optimal for many growers:
Vegetative Stage / Early Flowering Stage :

• High nitrogen
• Medium phosphorus
• High potassium

Flowering Stage:

• Low nitrogen
• Medium to high phosphorus
• High potassium

During the vegetative stage, you want to use high nitrogen. You can also opt for a general purpose plant nutrient as they tend to have high nitrogen levels.
During the flowering or bloom stage, you want to be using low nitrogen with a good amount of phosphorus and potassium. Having low nitrogen is important in this stage! Don’t use a general purpose nutrients, they have higher levels of nitrogen which discourages weed growth. Both phosphorus and potassium are important for your bud’s growth in the flowering stage. Phosphorus helps your plant grow more flowers and potassium helps with the weight of the flowers. Remember to keep the ratios balanced, having too much of either results in dead plants.

Organic Nutrient: Should you go organic?

Many people wonder if organic nutrients are better for their cannabis. Organic nutrients do have their benefits. Some people believe they get more fragrant buds from using organic nutrients. It’s natural, which could be important if you’re growing inside your home. But make sure you don’t use organic nutrients for a hydroponic set up. Organic nutrients can can spoil the water in your reservoir with bacteria or overgrowth of organisms. Chemical nutrients are the way to go for a hydroponic setup. Chemical nutrients also ensure faster growth and increase the potency of your buds.

Nutrients for hydroponic setup

Hydroponic setups grow plants without soil and is used by almost all indoor growers. Most people have reservoirs, or buckets that they fill with water and nutrients for their plants to soak up. Most cannabis nutrients on the market are sold specifically for hydroponic setups.
Now that you know more about nutrients, let’s dive into the best nutrients for growing cannabis.
