Getting the best cannabis nutrients will depend heavily on the environmental conditions and cannabis nutrients provided to them. Get the feeding schedule and grow room conditions wrong and you will severely compromise harvest quality and yields.

One of the most common mistakes in cannabis cultivation is the tendency, especially for less experienced growers, to over-feed (and over-water) their plants. This reduces root growth below ground and can permanently stunt (limit) growth above ground. Your goal should be to keep your plants in the nutrient ‘sweet spot’, without underfeeding/overfeeding, from seed to harvest. This guide shows you some ways to do just that.

Macro and micro cannabis nutrients explained

 

The most frequently discussed cannabis nutrients tend to be the main ‘NPK’ macro nutrients. These are the base cannabis nutrients which tend to be rich in the key minerals Nitrogen (N), Phosphorus (P) and Potassium (K).

NPK based nutrients provide the essentials for cannabis plants, just as protein, carbohydrates and fat are basic dietary ingredients for many animals. In addition, cannabis can absorb Carbon from atmospheric Carbon Dioxide gas (CO2) as well as Hydrogen and Oxygen from air and water.

But cannabis needs much more than just the essential minerals. This is where the micro nutrients are important. Micro nutrients are the trace minerals and vitamins required which allow your plants to achieve optimum health and growth. This includes elements such as Copper, Boron, Manganese, Calcium, Magnesium, Iron and many others.

More complicated organic compounds and vitamins, such as Fulvic acid, Humic acid etc also greatly help your cannabis plants. The choice of cannabis nutrient brands is extensive and each manufacturer has their own closely guarded recipes.

Cannabis micronutrients

By definition, cannabis micronutrients are not required in high concentrations. But they are vital and an absence of micronutrients could result in serious issues. There are many micronutrients, here are some of the more important
