Copper is a micronutrient necessary for plants in very small doses. It is allowed for organic farming and for the cultivation of marijuana plants. Copper activates enzymes involved in lignin synthesis and is essential for various enzyme systems.
In addition, it intervenes in the process of photosynthesis, essential for the respiration of plants and helps them in the metabolism of carbohydrates and proteins.
Benefits of Organic Copper Fertilizer
The Vegetal Bioplant laboratory has developed an organic copper fertilizer for marijuana plants, with its use the following benefits are obtained:
- Intensifies the flavor and color of the buds.
- It acts as a preventive fungicide, on the appearance of fungi and certain bacteria.
- Nutritional contribution for plants, since they absorb it and copper is involved in various processes such as the biosynthesis of chlorophyll.
- Fertilizer that improves the quality of crops.
- Natural product with preventive action.
Copper deficiency in plants
Like most nutrient deficiencies, symptoms of copper deficiency occur on new leaves.
These symptoms vary depending on the type of crop, in marijuana they usually start by rolling up and a slight chlorosis. Within the chlorotic zones of the leaves, small necrotic spots may form, particularly at the edge of the leaves.
As symptoms of copper deficiency progress, new leaves grow smaller and smaller, lose their shine, and in some cases may wilt.
Side branches may also be affected. The appearance of the plant may seem compact and the stems between the leaves are shortened; while the buds usually have a lighter color than normal.
The excess of other nutrients, such as phosphorus and potassium, or other micronutrients, can also cause copper deficiencies in the plant.
The deficiency can also occur due to a high pH level in the substrate, since its availability will be lower for the plant.
Excess copper in plants
We can also exceed the supply of copper for the plant, in this case, the high levels of copper in the substrate can affect root development; causing it to have excessive lateral growth.
When a plant has high levels of copper, it can compete with other nutrients in its absorption, such as iron, and sometimes molybdenum or zinc.
If the copper toxicity is not leveled or corrected, we run the risk of reducing the branching of the plant and consequently causing the deterioration of the marijuana plant.
As can happen with other micronutrients, the availability of copper is greater when the pH of the substrate is low, if symptoms of excess copper are detected, it is necessary to analyze the pH of the crop substrate.
How to apply copper fertilizer to plants
The deficiency or excess of copper is what we must avoid at all costs, neither of the two extremes is good, and the quality of the crop could be affected in both cases.
At Madame Grow we always want your marijuana cultivation to be professional and that is why we have an irrigation table for each type of fertilizer and phase of growth or flowering.
It also depends on the type of substrate you choose. With a normal substrate, the range that copper should have is 0.05-0.5 ppm, while in fabrics it is 3-10 ppm. Compared to another type of micronutrient, for example, the level of iron in the tissue is 20 times higher than that of copper.
Our organic copper fertilizer is liquid and therefore soluble in water and controlled release. It should be applied in the rates recommended by Madame Grow:
Add between 0.5 and 1 ml per liter of water, once or twice a week until deficiencies are corrected.
