Cannabis Nutrient Burn Fix: How to Resolve and Prevent It

What is a Nutrient Burn?

A nutrient burn occurs when cannabis plants absorb too much of a nutrient, usually from overwatering or using water with high nutrient concentrations. This leads to visible damage on the leaves.

Identifying a Nutrient Burn

Look for brown or black spots on the leaf edges or tips. The color and shape of the spots can help determine which nutrient is causing the burn. For example, iron deficiency often causes speckled yellowing.

Fixing a Nutrient Burn

1. Adjust watering: Ensure the soil is not waterlogged and allow it to dry out slightly between waterings. 2. Change nutrient solution: Use a balanced nutrient formula and follow the recommended dilution rates. 3. Flush the system: Rinse the roots with clean water to remove excess nutrients.

Preventing Future Nutrient Burns

• Use pH meters and EC meters to monitor water quality and nutrient levels.
• Follow a feeding schedule and adjust it based on plant stage and environmental conditions.
• Choose the right nutrients and supplements for your specific cannabis strain.
