Am I ever humbled. In another life i use to study plants a lot. I have russet mites and it is what I had last year and I was too stupid to figure it out. They look very much like thrip only with thrip you can see them with the naked eye. Russet mites you can only see with magnification. I use those 60 X power. Russet mites like hot and dry climates. The leaves taco like heat stress. I didn't see any big signs on the leaves but when the plant starts to flower the flowers turn brown prematurely. I am heart sick. The inside seed project I have is in danger I am fairly sure. I haven't gone in there today. I looked at the mites with my microscope and I really want to swear here. They have these two insidious lobster claws like appendages coming from one end. ( think Joe Cocker) sorry, I am delirious. The treatments are many and not too good. I will be using sulfur outdoors first and then beneficial's and who knows what else.. Oh, I have some Dr Zyme or something coming. They are very hard to kill and trying to do it organically may be more of a challenge, I don't know. I just spent a year buying pot for myself because of last summers grow. I don't want and can't do that again.
