Nutrient Deficiency: How to cure Nutrient Deficiency on cannabis plants

What is a nutrient deficiency?

In general, different symptoms describe the extent of nutrient deficiency in plants although there are some common symptoms that are associated with more than one deficiencies in the plants. Each nutrient performs its role in the process of growing whereas the deficiency symptoms are grouped in 5 classes according to their effects on the plant’s growth that is stunted plant growth, Chlorosis, Interveinal Chlorosis, Leaf discoloring, and Necrosis.

What causes major nutrients deficiency?

Imbalances in the movement and supplies of the nutrients to different parts of the plants cause stunting whereas chlorosis and interveinal chlorosis appear when the plant nutrients needed to perform the photosynthetic activity are deficient in the demanded place. Chlorosis in plants turns leaves a light green to yellow with white and yellow spots on plant foliage. Interveinal chlorosis occurs when plants are deficient in Boron, Ferrous, Magnesium, Manganese, Nickel, and Zinc. Purple-reddish coloration in plant leaves and sometimes in the stem may occur due to the accumulation of the pigment anthocyanin due to stress or disrupted functions while the same symptoms may appear at the time of maturity and weather change that is hard to differentiate. Necrosis generally transpires in later phases of a deficiency and causes the plants to turn brown and ultimately die. Since a sum of nutrient deficiencies yield similar signs and symptoms, a detailed evaluation of symptoms related to exact leaf shapes or positions on the plant will be discussed later in the article regarding Symptoms, causes, prevention, and remedy for each deficiency meanwhile let’s see the best possible solutions to overcome some common deficiencies in the plants;
