If you're cultivating cannabis, you may have noticed brown tips on the leaves. This is a common issue that can be caused by a variety of factors. Understanding the underlying causes can help you resolve the problem and promote healthy plant growth.
Causes of Brown Leaf Tips

- Underwatering: Water deprivation can also cause leaves to wilt and turn brown.
- pH imbalance: The pH of the soil or hydroponic solution should be in an optimal range for nutrient absorption.
