Alot of mites get dragged into their store from the clothes of growers bringing them from other grows, any place that sells clones is going to be plagued with mites. This is just part of the game. You can't stop them, you could have a couple thousand in the cuff of one persons jeans. Key is to not bring fresh cuts into a grow room. the mites need lots of fresh vegetation to multiply otherwise they are colonizing some gangly cuttings which doesnt last long. If my cuttings had mites, the fact that there were no plants already in the room, there wasnt a habitable environment for pests to survive. Have an isolated veg chamber across your property if you expect to bring in cuts from a storefront. Otherwise bring in that first round, and make clones of those clones. Get one of each strain u want as moms and dont expect to have a constant cycle of fresh store boughts unless you quarantine them. That's my two cents. I know I had mildew already but it was more likely to be caused by me. I know if the cuttings had mites, they prob arent super mites, but just fresh mites brought in AFTER the clones were dipped the night before. Common sense here people, no government dea conspiracy tinfoil hat shit.
I came here expecting the worst, but also hearing decent stories. My experience, as long as the mildew was an isolated incident caused by me not having proper ventilation.... then so far has been really good and the genes are definitely pretty solid, the kryptonite cut is gnarly.
Also the leaf curling can be PH and taco'ing is a nutrient issue. When you are on a fox hunt, you'll be barking up every tree. Yes could be some remnant of a broad mite infection or could be what more commonly causes such symptons.
This is my OPINION. and you know what they say about those. ;)
