This chapter describes the nutrient requirements of the cannabis plant. It also describes the problems that generally appear, when deciding on feeding schedule for nutrition for your marijuana plants. The important point explained here is your weed plants will require some important nutrients, which can be classified into micronutrients and macronutrients.
Macronutrients include nitrogen, phosphorus and potassium along with the naturally available carbon, hydrogen and oxygen. Nitrogen is essential for the normal growth of the plant. Phosphorus is required for energy transfers and for the development of the cannabis flowers. Potassium is essential for producing complex carbohydrates in cannabis, among other plants and is need for the formation of marijuana flowers.
Most companies employ the N-P-K (Nitrogen, Phosphorus, and Potassium) ratio to describe the available macronutrients in fertilizers. A perfect balance of these ingredients ensures that your crop does well during all the phases of growth of marijuana. You can also think of N-P-K throughout the life cycle of a cannabis plant as N-roots, P-stems, K-flowers.
Calcium, magnesium and sulfur are also required in trace amounts for the healthy growth of the cannabis plant. Calcium is important for detoxifying plants. Magnesium is essential for the creation of chlorophyll, which is required for plant photosynthesis. Sulfur is necessary for a growing plant, as it is required to create complex structural proteins in weed.
There are also other elements required in minute quantities, such as iron, copper, manganese, sodium and zinc for great marijuana growth. They are usually available in ordinary garden soil. Iron and copper are required for synthesizing chlorophyll, while manganese is essential for the photosynthesis process. Some plants require sodium for controlling the stomata on their leaves. Zinc, on the other hand, formulates important enzymes which control important plant functions.
Boron is another important element, which is required in minute quantities. Otherwise, it causes toxicity in the weed plant. It is required for entering the flowering stage and important cell division.
The cannabis plant also requires the soil with a particular pH level. This level should ideally lie in the range of 5.6 to 6.3 on the pH scale. According to researchers, the ideal value of soil pH should remain just above 6 for excellent growth and complete absorption of the essential nutrients.
You cannot provide all the required nutrients in a random manner to a cannabis plant. This practice often produces nutrient burn. This concept describes the excess availability of particular nutrients to the plant, which in turn stop the normal growth and make the plant enter a dormant period, with damaged leaves and flowers.
Nutrient burn occurs when the water that you are giving to your marijuana plant contains additional nutrients, which are not good for the plant. The leaves can get crunchy and lose their original color at the edges. The right way to rescue the plan, is to flush out the soil with water that has neutral pH. Once the cannabis plant roots are clean, you should leave the plant for a few days, and then once again start to add the required nutrients in the right quantity. An important tip for growing cannabis is that more is less when feeding your marijuana especially after you are trying to bounce back from nutrient lockout.
