Powder mildew is a now common occurrence when you try to grow cannabis. I just took this girl down today after seeing powder mildew creeping in on leaf.
You can see powder mildew on middle water leafs, it's white as powder sugar
The weather this harvest is great besides the morning mist. Luckly I live high enough the mist doesn't touch my plants for long. Still long enough to make powdered mildew on some of my plants I still need to take down.
