Cannabis leaves with yellow tips often indicate a nutrient burn, which can be caused by overwatering, incorrect pH levels, or excessive nutrient use.

Common Causes of Nutrient Burn
- Overwatering: Excess water can dilute nutrients, leading to nutrient burn.
- Incorrect pH: pH levels outside the optimal range (6.0-6.5) can cause nutrient lockout.
- Excessive Nutrients: Over-fertilizing can lead to nutrient burn, as plants absorb more than they need.
How to Cure Yellow Tips on Cannabis Leaves
