In this post we will focus on the macro and micro-nutrients necessary for the development of cannabis plants. These elements are available in the nutrients, so the chosen type of fertiliser and its correct use will lead us to a crop without deficiencies or excesses, thanks to a properly planned and balanced feeding.
Sulphur:
Potassium:
Copper: This element is actively involved in the metabolism of the plant and in the creation of carbohydrates, also helping in the production of sugars and proteins. In the case of a deficiency, this must be treated by watering with a mineral fertiliser rich in copper.
Iron is a necessary nutritive element for plants since it’s directly related to the use of energy by sugars. It’s easy to find iron deficiencies in plants grown in alkaline soils. This deficiency tends to be present in soils with a PH level above 6.5. Early symptoms can be observed in the youngest leaves, which turn yellowish while keeping green veins. If the deficiency continues, the plant will suffer serious defoliation.

An iron deficiency can be preceded by a nutrient lockout caused by an excess of copper. Other elements like zinc or manganese can cause a null absorption of iron by the plants, which will in turn cause several deficiencies. To solve an iron deficiency, avoid watering with fertilisers that contain high concentrations of Mn, Zn and Co, and also reduce the PH level of the nutrient solution to 6.0-6.5.

This post shows the main deficiencies and excesses of macro and micro-nutrients that can affect our cannabis plants during their cultivation. If you d
