Nutrient burn in marijuana plants is a common problem that can occur due to over-fertilization. It is a condition in which the plant’s leaves turn yellow, brown or crispy. The tips become burnt, due to excessive levels of nutrients in the soil. This condition affects the plant’s ability to absorb and utilize nutrients, leading to stunted growth and reduced yields.
Nutrient burn is often caused by the use of fertilizers that are too strong for the plant. Also by applying too much fertilizer at once. This can result in an accumulation of salts and other nutrients in the soil that are toxic to the plant. The excess nutrients can cause the plant to become “burned” and the roots can become damaged. This reduces the plant’s ability to absorb water and nutrients.
To avoid nutrient burn, it is important to follow a proper fertilizer regimen. Use the right type of fertilizer for the stage of growth the plant is in. It is also important to monitor the plant’s nutrient levels. Use a pH meter to ensure that the soil is not too acidic or too alkaline. The pH should be between 6.0 and 7.0 for optimal nutrient uptake. Additionally, it is a good idea to use a high-quality soil mix that contains the right balance of nutrients. As well as a good-quality water source.

If a plant does develop nutrient burn, it is important to address the issue as soon as possible. The first step is to reduce the amount of fertilizer being applied, and then flush the soil with water to remove the excess nutrients. This can be done by watering the plant thoroughly. This allows the water to drain out, and then repeating the process several times.
Once the soil has been flushed, it is important to give the plant time to recover before applying any more fertilizer. If the plant is still showing signs of nutrient burn after several days, it may be necessary to remove some of the damaged leaves. This will reduce stress on the plant.
In severe cases, it may be necessary to repot the plant into fresh soil to ensure that it has a healthy environment for growth. If the roots have been damaged, it is important to carefully prune them, removing any damaged or dead roots, and allowing the plant time to recover before fertilizing again.
In conclusion, nutrient burn is a common issue for marijuana plants, but it is preventable. By using the right type of fertilizer and monitoring the plant’s nutrient levels, growers can avoid this problem and ensure that their plants grow healthy and produce a high yield. If nutrient burn does occur, it is important to address the issue promptly and give the plant time to recover.
