What is Powdery Mildew?
Powdery mildew is a common fungal disease that affects cannabis plants, particularly during cooler and more humid conditions. It can lead to decreased plant health and yield if not addressed promptly.
Early Signs of Powdery Mildew
- White, fluffy spots on the undersides of leaves.
- Yellowing and wilting of leaves.
- Discoloration of leaves, often with a powdery white or gray coating.
Preventing Powdery Mildew
Prevention is key when it comes to powdery mildew. Here are some tips to keep your cannabis plants healthy:
- Air circulation: Ensure your grow space has good air flow to prevent humidity buildup.
- Proper watering: Avoid overwatering and water the base of the plant rather than the leaves.
- Disinfect tools: Clean your pruning tools between uses to prevent the spread of spores.
