Hey guys I've been battling mites for some time now about a month I don't want to say what I use. I've been to a few local hydro stores 3 rec azamax and 1 rec forbid and 1 green clean.
Well if there just spider mites you can alternate with azamax and a higher end neem oil like Einstein . This is the "organic " route, and you have to be persistent and spray every few days.
If you want to go the chemical route get avid and forbid spray once and done!
