  1. Anyone got any links to some good powdery mildew treatment, i'm about 3 weeks into flowering 4 california hash plant clones taken from the original california hash plant seed I had grown prior to this grow. Lots of vegatative growth with little aeration is what i believe caused powdery mildew to start forming on some of the leaves. Could use some help in this problem, already thinned out the plants for better air flow....any kinda sprays i can use?
  2. should i try neem oil/water spray or milk/water spray?
  3. I use h2o2 2-5% per liter in a pray bottle then spray down and wipe clean. I also like to wipe down the stems because i can usually find alot their.
