I have rampant powdery mildew. I have 2 dehumid + air conditioner, temp is well regulated. Can't figure it out. Any other suggestions? My big question is I also had it in veg and sprayed twice with neem, it worked quite well for about two weeks each time, now those plants are in flower and I have alot of leaves yellowing and dying- ph is good, ppm is good, I saw somebody say that neem can clog the underside of the leaf, could this be the yellowing? All suggestions and comments would be welcome! Thanks.
