Ok bro, Heres what u do. While you add lots of N, be sure to ad lots of P as well as K.:S2:ROFL Damn I'm a smart-ass. lol But seriously.. Try starting out with some cfl's rather than a tube, a series of them put out very good lumens and wide spectrum. Switch over to the HID when you start feeding. I have a 400 hps with a tube and 210 cfm centrif fan in my closet space, it gets 72-74 deg. I would think a pair of 4 hundies with bat wings would get way higher than 87-88 deg but still kinda high for seedlings IMO, may be causing issues. Combined with hot, damp soil may be showing some sort of wilt/damping disease(fusarium, verticillium, pythium). All in all, I think Ciggs, Finn, shake and Rusty has you hooked up....they have a habit of that shit.lol:greenthumb: Also, your soil can still dry out after/while wilt occurs from some evap appearing dry later.
