I have a very small bit of powdery mildew on the girls. I have been using CuSo4-copper sulphate about every 3 days to keep it at bay. It seems to be working really well. They look great, are happy and are working hard on plumping up their flowers. I have 4-6 weeks until harvest would be my guess. Fingers crossed I can keep the effing PM from taking over. 😬
