I'm not seeing what you're seeing. Only thing I can think of is fertilizers in the soil. Ride it out, your T5 lighting could be just a touch closer, and you need a circulation fan in there to strengthen your stems.I have been looking all over the forms for hours and my question may sound mundane but I have two White Widow seedlings about a week old. The fringes of the leaves are starting to curl up what would cause this they are under a t5 HO light at about 2 inches away at a temp of 78 F. What would cause this?

You need an intake hole for sure. Your fan probably doesn't work well with a negative pressure (lower pressure inside the box because you're pulling out hot air but not replacing it with cool air).Hey I just started an experiment with a speaker box and I set it up with some reflective material I got 2 seedlings going about 3-4 days old with one fan and 2 23 watt cfls...temps are getting extremely hot over 100 f the speaker has an exhaust hole wit the fan blowing out. But its not working ....anything I can do how bout. Sum water wit ice on da side..
Add an intake hole and fan and you'll see the temperatures drop.
Bottom line though, the solution is moving more air and having more ventilation to exhaust that hot air and replace it with cool air.
