I usually do not like applying fertilizers on my plants. Sometimes, however, I have to give in and use them in order to provide the extra nutrients that my plants need. In such cases, I always go for organic fertilizers because they do not compromise the safety of my plants. Organic fertilizers promote the growth of healthy marijuana buds. The best part is that they rot back into the soil, thus adding to the organic matter!

With states continuously legalizing weed, there has been an increasing demand for weed fertilizers. This is why I am reviewing 5 top products to help you find the best organic fertilizer for cannabis. Before delving into the products, however, here is a buying guide to help you make an informed purchase.

Here are the marijuana organic fertilizers we’ll be reviewing:

Benefits of Organic Fertilizer for Weed

  • Increases soil nutrients for increased bud volume and health
  • Increases weed potency
  • It rots and breaks down into the soil to add organic matter to the soil structure
  • It reduces soil acidity and does not cause leaching

Things to Look For In the Best Organic Marijuana Fertilizer 

When looking to buy the best fertilizer for cannabis, there are a few factors you need to look at to ensure you get the best one for your plants. These are:

· Solubility

The best weed fertilizer should have water-soluble nutrients. It should be soluble in water in whatever form it is, whether liquid or solid since it needs to flow into the plant. The root systems are the best uptake for cannabis fertilizer and they easily absorb liquids.

· Organic components

Weed requires numerous elements. However, it depends on three critical ones. The key mineral components that are essential for weed are nitrogen, phosphorous, and potassium. Ensure that your fertilizer has NPK, which are the symbols for the three elements. Below is a brief of the importance of each element.

  • Nitrogen: Nitrogen is critical for the flowering process and photosynthesis. The process of photosynthesis converts carbon to sugar, generates chlorophyll, and promotes faster growth. Nitrogen is also obtained from manure and blood meal among others.
  • Phosphorous: Phosphorous is critical at the flowering stage because it provides the bud with volume, density, and good health.
  • Potassium: Potassium promotes bud bloom and strengthens the immunity of your plants.

· Additional nutrients

As mentioned above, there are numerous nutrients required when growing weed. Some trace minerals critical for growing marijuana include Chlorine, Boron, Zinc, Iron, Copper, and Manganese. These nutrients aid in crop growth and potency. The best pot fertilizers will have all of these essential micronutrients that are important for long term crop development.

Best Way to Use Fertilizer for Weed

Before anything else, dissolve the weed fertilizer in water. Use the recommended measurements to avoid putting too much of it. Too much marijuana plant food is dangerous to your plants.

Next, spray large leaves with the fertilizer solution. Additionally, spray leaves that show signs of nutrient deficiency. After spraying, water the plant accordingly. Remember that too much water is not good for your crops.

Avoid using concentrated mixtures by only applying every 2 weeks until flowering. 2 weeks before harvest, flush all the fertilizer out of the soil using water. Moreover, you will need to remember that NPK fertilizers lower the soil pH, which means that you need to keep adding calcium as required.
