Cannabis Fertilizers: The Super Guide

The world of marijuana fertilizers is wide and complex, full of technicalities, measurements, indices and formulas.

Fortunately, there are products aimed at inexperienced, advanced and ultimately expert growers.

This guide gives you what is necessary to understand the bases of fertilization, understand what each product consists of, how to use it and at what time.

The fertilizer for marijuana can be ordered in various ways, but there are three broad categories :

  • According to its origin (origin),
  • Based on its function (time of application),
  • Finally according to its format.

Technically additives and fertilizers are different things, although for this post we will refer to them as a whole. But first, let’s start by talking about its importance.

Cannabis Fertilizers: The Super Guide

The importance of fertilizers for the cultivation of marijuanas

Unlike what the popular saying says, the earth does not always have everything that plants need.

In particular, marijuana growing substrates are designed to provide a comfortable place for the roots, but do not have the necessary nutrients for the entire growing process. For example, Light-Mix type substrates only have the necessary fertilizers for 2 weeks of cultivation, after that period, they are drained by the irrigation water or absorbed by the plant.

If we want our plants to have everything they need, we must use products that deliver a wide range of nutrients.

These can be divided into macro-nutrients, which are the “structural” elements of the plant, and micro-nutrients, which have metabolic and other functions. There are micro-nutrients of more or less importance, but without the macro-nutrients our girls simply would not grow.

Types of fertilizers according to their origin

Here we can divide fertilizers into three groups according to their origin:

  • Organic fertilizers of totally natural origin.
  • The Fertilizer  Mineral chemical origin.
  • The bio-minerals, which are only a combination between the other two groups.

Organic fertilizers

All its composition is of biological origin. Whether they are plants, fungi, algae or guano, they are usually mixtures of different components combined to achieve their function.

Since they come from living things (or their wastes), the variety of nutrients that compose them is much greater than mineral fertilizers, and this has several consequences.

A very positive aspect of organic fertilizers is that the buds they produce taste better than those fertilized with chemicals, are more complex in their aromas and tend to produce less itchiness.

In terms of cultivation, organic fertilizers are absorbed more slowly than chemical-minerals, so their result is less immediate, but they are also easier to apply, since there is less risk of over fertilizing, saturating or poisoning our seedlings..

This does not mean less growth, organic fertilizers can achieve just as good results as their chemical peers, and they have the grace to be friendly to the environment.

The companies that produce them usually have organic certification.

If you are starting out in growing marijuana with an indoor or outdoor kit, we recommend this type of product, as it is more difficult to make a serious mistake.

Mineral or chemical fertilizers

These have a non-biological origin, but can have surprising and fast results since they are absorbed more directly by the roots.

Its components are targeted to specific functions and come highly concentrated, so making the mistake of over fertilizing is more likely than using organic fertilizers.

The dosage of this type of products must be very precise, and requires constant monitoring of our plants.

In addition, the application of enzymes that help the marijuana plant to integrate these nutrients is recommended.

Additionally, they require a good washing of roots so that the chemicals are not deposited in our plants.

The use of products such as Royal Flush from Humboldt Nutrients is recommended for a better wash.

Note: If smoking a bud is not itchy and the resulting ash is light gray, it means that the root washing was successful. On the other hand, if your throat itches when you smoke, and the ash is black or with a slightly pasty consistency, it is due to the stagnation of fertilizers and the lack of root washing.

Type of fertilizers according to their function

As you already know, the life cycle of a marijuana plant consists of three fundamental stages and there are fertilizers for each of them:

  • Rooting Stage: Rooting Fertilizers.
  • Growth Phase: Growth fertilizers (Grow or Veg).
  • Flowering Stage: Fertilizers for flowering (Bloom)

There are many fertilizers for each stage, but they basically fall into the categories described below.

Rooting

As its name says, its function is to stimulate the growth of the roots.

This is achieved by delivering key nutrients and some phytohormones related to root promotion.

They are usually started to be applied when we already have a stable seedling (10 to 15 cm, or 2 to 4 leaves), and after each transplant.

They are highly recommended since, the greater the number of roots, the greater the absorption of nutrients and water.

If we manage to have good roots from the beginning, our plants will benefit throughout the process.

Note that the seedlings are very delicate small, so the dosage must be careful.

Here we detail some of the most recommended roots:

  • Rhizotonic – Canna
  • Root Complex – Hesi
  • Power Zyme – Hesi
  • Power Roots – Plagron
  • Pure Zyme – Plagron
  • Deeper Underground – Top Crop
