i still say mites,ive had leaves do that to me before,all the way to the little stems in the leaves and looked all deformed..only bugs to ever be spotted were mites..
sounds like white flies try getting the air moving faster around the plants. if not white flies maybe thirps they are a larva type for a while then they get wings and fly aroundThe only bug that i am seeing is when i water them you can see (sometimes) little flying bugs fly up from the soil...Then you can see them trying to get back under the soil...
