thanks for the tips. We are currently having a major issue not with the mites but with some root rot. We changed the nutrients 2 days ago only to find slimy shit all over the roots. The largest plant has nearly all of it's fan leaves turned to yellow and falling off. The buds have very little crystals on them while the other plants' buds are getting fairly large and compact. We were thinking about harvesting the big plant but I think we might just end up harvesting everything at once in stead.
