What is a Nutrient Burn in Cannabis Plants?
A nutrient burn occurs when cannabis plants absorb too much of a specific nutrient, leading to leaf discoloration and stress. This guide will help you identify and treat nutrient burns.
Causes of Nutrient Burns
- Over-fertilizing: Excess nutrients can overload the plant’s ability to absorb them, leading to a burn.
- Incorrect pH levels: Imbalanced pH can affect nutrient availability to the plant.
- Poor water quality: High levels of salts in the water can cause a burn.
Identifying Nutrient Burns
Look for signs of nutrient deficiency or toxicity, such as leaf discoloration, leaf edges curling, and leaf drop. Different nutrients cause different symptoms.
How to Fix Cannabis Nutrient Burn
Treatment and Prevention
1. Flush the System: Water the plants with clean, pH-balanced water to dilute excess nutrients.

3. Adjust Fertilization: Reduce the amount of fertilizer you are using or switch to a lower-nutrient formula.
4. Monitor Water Quality: Use filtered or RO water to reduce the risk of salt buildup.
