The process of growing cannabis requires use of appropriate nutrients. One of these solutions is potassium which boosts growth of plant roots. This substance also promotes photosynthesis. Potassium (potash variety) refers to the earliest-acknowledged nourishment aside from manure.
Marijuana plants need this alkaline potassium compound during the flowering stage. It comes after increasing phosphorous and reducing nitrogen. Potash helps the light-withdrawal cycle trigger the transition from vegetative growing to formation of flower buds.
This brief article shows how potash can become a valuable fertilizer for cannabis growing.
Potash stands for the K in NPK (Latin term “Kalium). It refers to the third of essential macronutrients. These elements play a variety of roles for healthy Cannabis growing. It includes early growth, enhancement of disease resistance, and augmenting efficiency of water utilization. Optimization of potassium levels help repel pathogens which reduces the susceptibility of pot to milder and other infections.
In growing cannabis, potash deficiency can produce negative consequences. Growers must be prepared in preventing and resolving any shortage of this nourishing substance. Potassium helps boost density, weight, and volume of the nugs. Deficiencies seldom take place in hydroponic systems or water-based technologies. Check the system carefully once you discover symptoms before implementing any treatment.
Insufficiency of potash usually happens in soils as well as other mediums. Brown or yellow colors at the edges of leaves and tips comprise the most common symptom. Over time, the leaves curl or look charred like lack of iron. Stretching is another possible indication. Plants taller than others mean stems may turn out weak. This is not a good sign.
Next, spots will gradually appear on the leaves. More marks will emerge if growers do not administer any remedy. Unlike most deficiencies, the leaves’ veins remain green in color. However, stems and petioles or stalks connected to the leaves begin to show red tones.
Surplus of potash does not produce positive effects as well. Too much of the nutrient obstructs the inclusion of other minerals like calcium, iron, manganese, magnesium, and zinc. The overabundance produces darker colors in plants. It normally leads to other deficiencies. To deal with this issue, wash the roots to absorb the nutrients. Fill the water container with three times more than the average capacity.
Functions of Potash
Potash bolsters the strength and consistency of tissues during cannabis growing. Said nutrient also enhances resistance of marijuana plants in case of drought. Here are other functions of potassium in weed cultivation:
- Participates in photosynthesis by improving the fusion of carbohydrates.
- Helps facilitate synthesis of amino acids and proteins. The acids originate from nitrogen in ammonium form. Interaction between the two substances becomes crucial to various metabolic processes of cannabis plants.
- Potash also works with phosphorous to increase the root system’s resistance.
Potassium takes responsibility for the modulation of the plant’s intracellular environment. It maintains ionic character, buffer pH which specifies acidity, and promotes favorable reaction.
