How do a post a question on here? I just found this web site and signed in. I have 15 real young (babies) white widow veg plants on a 3x6 tray and 3 hps 1000 watt lights. My top leaves are curling back and the veins are rigid. The leaves are real light green. My buddy has the same babies out door and he's not having any problems, his leaves are dark smooth and flat. Last night I shut my middle light off and raised the other two, but today it didn't change after 18 hours they looked a little worse. My PH is at 7. soil ppms at 470. temp is kept between 70 and 80. humidity is kept at 50-55. I use pure co co, and real light nutes right now. I don't have a camra (I went in the water with it the other day)
