your ph is wayyyyy to high, I'd just use the tap water and I use concentrated lemon juice to lower my ph, which no one here has told me is a bad idea, so thats what I'm gonna suggest. Also how many bulbs you runnin? Watts? Do you have some pics of your box? What growing medium are you using? Are you giving them nutes? These are the types of things you should include if you want help from the cannabis gurus around here, although it seems this forum was practically made for lurking. You need 20 posts to add pictures, but if you have a photobucket account you can just link them from there, which is what I do.
