Like any other plant, the cannabis plants you buy from may get subjected to pests, fungal infections, viruses, and several other disadvantageous problems for the quality and size of the harvest. Unfortunately, in most cases, the inexperienced growers often struggle to correctly identify the issue and miss identifying issues like nutrient deficiency, pests, molds, and water issues.

Leaf Margin Rolling

The most common cause of leaf cupping or margin burns is overfertilization. If the plants receive more food than their size, vigor, and growth rate, then there is a fair chance that the plant will start by showing moisture stress in the leaf margins and trips reflected by the burning. 

The other symptoms include showing copper-colored necrotic spots or the leaves’ hardening, giving it a crisp feel. When the concentration of salts in the solution is more than the salinity level of the plant’s tissue, the water is drawn out from the plant across the root gradient to fix the ppm imbalance. It follows a natural osmotic response called IOW that helps to equalize the roots’ salinity levels on the epidermal levels.

Over-fertilizing can also lead to the burning of sensitive tips and hair, leading to nutrition deficiency and increasing the salts’ concentration. Flushing helps to get rid of the excess salts.

Leaf Margin Cupping

Excess heat makes the plants lose water faster than the root system replaces it. It leads to leaf margin cupping or rolling to conserve moisture. To solve this issue, you need to develop a large and robust root system by practicing the most sound cultivation techniques. An effective root system helps prevent the leaves’ desiccation due to the heat by supplying the required moisture to keep the plant healthy. Even a short episode of heat can permanently destroy the leaf tissues, especially those located at the top.

Bleaching Of Leaves

Before you buy the top-quality seeds and plants from, remember that the cannabis plant can’t withstand too much light. You need to keep them under a shade or reduce the availability of sunlight. 

It leads to collecting debris and dust particles on the leaves due to the plant materials and the different weather conditions like rain and cloudy conditions. Too much sunlight leads to bleaching of the leaves, which in turn destroys the chlorophyll. Make sure that your plant receives less sunlight during the flowering stage as compared to the vegetative stage.

Rooting Of Roots, Leaf Stressing, And Stunted Growth

Overwatering causes the weakening of the root system as it deprives the roots of proper gas exchange. The roots do not get enough oxygen supply, which leads to an anaerobic condition that causes root decline and shows up as leave stress, stunted growth, and death in severe cases. 

Conclusively if you plan on cultivating marijuana, it is essential to know the various symptoms that your plant is displaying and at the same time also know the different solutions and how to implement them to help raise your plant’s health.
