So you were able to get them under control and get a decent harvest? Nice work!!
I too started with infested clones and mothers. I've used pyrethrin foggers, neem oil, Organicide, and no pest strips, and seem to have gotten rid of them. Every once in a while I found spots on a leaf or two, and even a few eggs in my latest flower period, but never actually saw a mite. I think maybe the spiders in my basement kept eating them before they got very far. I was so proactive once I found them that I don't even know which of the many methods used did the trick or some combo of all of them. No apparent effect on my yield from either mites or control measures, although the Organicide really raised my nitrogen level in conjunction with regular veg feeding (ppm over 2000 in runoff water) and I had to flush them all which sucked. I thought I killed them.
