Dude though I'd take a gander at what ya got growing on. Seen the word mites,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ouch bummmer. Thick mites? Or hopefully fewer mites. Once them buggers find pot they set up shop. Can't say I blame them but they are a pain. I need to look back and see what ya got but I take it you're doing a hydro. Hydro isn't anything near my strong point. But you might if you haven't already start adding silicon to your food. Stuff's suppose to help toughen up the plants skin against mites and mildews. Don't ask me if I can say it works, but I'm doing OK right now, knock on wood. And I'm almost free of all pests. But your plants are small right now and should be easy to get a handle on. Watch out which sprays ya use, you don't want to bite your nose off with resistant mites. Rotate sprays every once in awhile. like Neem two times then something different. Once mites are gone keep it clean. Maintance spray as needed or untill the second week or so of flowering. They have a product called mighty wash I think I'd use if, and when I see they buggers again. Fact I see afew on my A-Haze I got going. She's onley got acouple weeks and mites aren't real thick so I think she'll be fine. But I keep her off buy herself, not touching other plants. Something you won't be able to do.
I'd love to have the engery to do thing like what you got going. But for now I'll stick to pots. The Light you have is perfect for that table. I installed both my lights on rails. They are the best light saver there is. And hits the plants at all angles which is nice. I want to build 2 4X10 tables in my spare room. Just for watering purposes for now. If I had the energy. other words might be awhile before I do. GL with the Mites. I'll check back in atad Keepem Green
