IDD i've gotta agree again with SA silica blast is the shiz. Didnt even think to mention it but if u get some SB and put it in a spray bottle that works good with treating the soil and along the stem. I've been using it of late with my plants in coco and it seems to at least protect for over a week or so. Never tried spraying it for PM though i'm not sure that would "FIX" ur prob thats more of a preventive then a fix. Seeing that PM is actually inside the plant, and once u see it the plant is fuct.Still u should be alright PM reduces yields and slows growth. It's all about the 3 in 1.
