My girl has finally moved into flowering. I noticed a few weeks back tiny white flecks on the leaves. I initially thought white powdery mold, but it doesn't wipe off. It seems to be leaf damage not something on the leaf. I then looked at pictures and thought spider mite damage. I have sprayed her down with spinosad twice but it still seems to be spreading, plus I see no other evidence of spider mites. I have no idea what this is or what to do. She is a beast and I'm really worried my harvest is going to get ruined. Any help or advice that can be offered would be really appreciated. Thank you.
