  1. Had a problem for 2 years all my grows had no effect when smoked only slight effect, absolutly no potency. I had to dispose of it all. I tried to find an answer ,but I could never find out. had root rot, bud rot, powdery mildew.Fusarium, cured all but still my grow was worthless, everyone I asked gave me their opinion, but no help, finally I was talking to someone and was told my problem sounded like Russet Mites. Bingo; I researched it and found that the smptoms were the same as my grow because I had no trichomes ,the mites ate them.I used Diotomoaceous Earth dusted all my plants and soil. Checked with microscope no more mites after 4 days. I will wash all my plants with tea mixture, now I will release some predatory mites [ Galendromus occidentalis] and see the results, on the potency of my cannibus
