Cannabis growing involves various steps and processes that you have to learn in order to get the best results. There are different things that can go wrong during the process. It could be limited humidity, too much humidity, too much fertilizer, too much water, ozone exposure, pH fluctuations, mites, mildew, viruses, mold, and nutrient deficiencies.

These issues can all be costly for the cannabis grower. The good news is that most of these cannabis issues have a quick, easy, and simple solution. Let’s take a look at each of these issues.

How to Treat Common Cannabis Growing Issues

Heat Stress

Excess humidity can result in heat stress, but this is one of the cannabis issues that are easy to solve. This issue involves the yellow characterization of cannabis leaves where it turns brown if it is close to the light source. The yellowing begins in a thin line and goes around the edge of the leaves.

The brown spots which are close to the light source will oftentimes appear burned. The most common occurrence is when the cannabis grower places the marijuana plant close to the heat lamp. The least common occurrence is during outdoor cannabis growing where the temperature is hot and dry and water is inadequately given to the plant.

In order to solve this cannabis issue the grower has to reduce the heat. For outdoor cannabis plants, the grower should provide the plants with more water and a considerable amount of shade. For indoor cannabis plants, the cannabis issues are more complex. You could:

  • Add a small fan so that it blows across the top of the plants
  • Adjust where you place the heat lamps
  • Using an exhaust fan to vent out any hot air

To replenish any nutrients lost due to heat stress and to help the plans recover, add seaweed extract. Many cannabis growers think that this will prevent any instances of heat stress.

The Nutrient Burn

One of the other common cannabis issues is nutrient burn. This is especially true for new cannabis growers. This usually occurs after the overly abundant application of hydroponic solution.

In such a case, the nutrients given to the plants are reaching the root more than the plant. This happens when compost manure is used on the cannabis plants.

This is one of the cannabis issues that can be solved with a reduced level of nutrient in the hydroponic solution. If the grower is watering the plants by hand, the cannabis issues can be fixed by flushing the system or dilute the hydroponic solution with a large amount of alkaline regulated water.


Blight can seriously endanger the safety of your plants and leave them feeling blue instead of green

One method of treatment for blight is to use a beneficial strain of bacteria against it. Certain bacteria can actually enrich soil and prevent the spread of plant disease. For example, bacillus subtilis is a naturally-occurring bacterium that fights blight and other fungi. It is easily available online for use in organic marijuana cultivation.

Another simple but effective solution for blight is to apply potassium bicarbonate to the plants. Potassium bicarbonate, like its relative, sodium bicarbonate (baking soda) is an alkaline substance that is toxic to fungi.

Potassium bicarbonate is available from most garden centers. It is a white, powder-like substance. For best effects, mix 3 T. potassium bicarbonate 3 T. oil, and ½ tsp. castile soap in a gallon of water. Apply the solution to plants daily as a treatment for blight or a way to prevent its spread.

The best treatment for blight is to invest in prevention efforts. One easy way to prevent the transfer of fungi or bacteria is to ensure your plants are appropriately spaced. Not only do crowded plants fail to get enough light, but they also become warmer and more moist. This facilitates the growth and spread of blight-causing pathogens.

Conclusion on How to Treat Common Cannabis Growing Issues

To prevent mold and mildew, reduce the humidity level. Test water for pH level to avoid fluctuations and if you have to, adjust the pH level to an accurate number, usually between 6.2 to 7.0 in an outdoor cannabis scenario and 5.5 to 6.5 in a hydroponic system.
