What it is / How it shows up:
Nutrient burn, commonly seen in cannabis cultivation, manifests as yellowing or browning of leaf tips and edges due to excessive nutrient intake. This condition typically appears during the vegetative or flowering stages when growers overapply fertilizers. While nutrient burn can be identified by visual symptoms, it can also impact plant growth and reduce yield. Gardeners often notice this issue on plant leaves and may see it discussed in growing guides or cannabis cultivation forums.
How it’s measured or identified:
- Visible discoloration of leaf tips and edges.
- Leaf curling or browning.
- Stunted plant growth.
Use in context:
- "The new batch of plants showed signs of nutrient burn after the last feeding."
- "Our yield was affected due to nutrient burn last season."
- "To avoid nutrient burn, reduce the concentration of your nutrient solution."
Safety & compliance in Canada:
