Types of nutrients in the cannabis plant
Nutrients are substances that ensure the preservation and growth of an organism. By providing the appropriate nutrients to the plant, we can develop its full genetic potential.
There are two main classification groups:
Mobile nutrients: They are transported throughout the plant as needed. When the plant detects a deficiency, it transports the necessary nutrients to the affected area. Nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg).
Immobile nutrients: They always remain in the same place. Calcium (Ca), boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), silicon (Si), sulfur (S), zinc (Zn), molybdenum (Mo).
Knowing how to differentiate between these two types is the first step in determining whether we have a deficiency or an excess. For example, we could observe if there is a change in the upper or lower part of the leaves.
- Immobile nutrients show deficiencies and excesses in the newest leaves, at the top of the plant.
- Mobile nutrients show deficiencies and excesses in the older leaves, the middle part of the plant.
- Salt accumulation blocks nutrients, causing deficiencies or excesses.
- Overwatering the plant can drown or rot the roots, causing excesses or deficiencies.
- Maintaining a good drainage system is essential for healthy growth.
- We must avoid problems with air circulation, air ventilation, temperature, humidity, light, water, organic soil, and maintenance.
The cannabis plant needs the non-mineral nutrients Carbon (CO2), hydrogen, and oxygen. Carbon is fixed through photosynthesis. Hydrogen atoms come almost entirely from irrigation water. Oxygen is taken from the atmosphere and used by the plant primarily for respiration.
The plant also needs other nutrients or mineral nutrients These nutrients are absorbed through the growing medium and nutrient solution. Providing the necessary and appropriate nutrients will allow us to obtain the maximum potential from the cannabis.
Types of nutrients according to metabolic energy
We can also classify them according to the amount of metabolic energy they provide to the plant as follows:
Primary nutrients or macronutrientsants: Nitrogen (N), phosphorus (P), and potassium (K). These provide the metabolic energy most used by the cannabis plant and are the most important.
Secondary nutrients: Calcium (Ca), magnesium (Mg), sulfur (S). They provide less energy and work by improving the intake of primary nutrients.
Micronutrients or trace elements: Boron (B), manganese (Mn), zinc (Zn), iron (Fe), chlorine (Cl), copper (Cu), molybdenum (Mo), silicon (Si), and a few more. These are essential for achieving maximum potential and quality, as well as optimal development.
Cannabis plants can suffer from both nutrient deficiencies and excesses. We need to be able to identify these issues in order to control and resolve them. To learn how to detect them, you can visit our article on excesses and deficiencies.
These nutrients are available in fertilizers. At our seed bank, Genehtik Seeds, we have our own range of fertilizers and nutrients, Genehtik Nutrients, suitable for a proper and balanced diet.
