HELP!!! My plant is undercurling!!!

Help!!!

The plants leaves are curling under.

The leaves are a solid green, except for one leaf... but that was an error of mine the light was to close at one point, but that was 2 week back. This week, after i transplanted she wilted, but then became better once i turned the light off. Now it seems that everytime i turn the light on it wilts, and not a slight wilt it bends over completely..
What could that be?!

im still learning so i cant say much but check these links maybe ull find something

can you post more pictures from the side?...rob

my guess would be overwatering the pics in the FAQ section look like/sound like your description can you take pics?

sorry i meant more pics

mayby its wilting from the heat, dry roots or over watering. or leaving it standing in water. root rot

update....
Thank you to all those who tried....
However she dies.. passed away...
T_T...
I have started a new group of seedlings...
hopefully i have more of a chance now..

Looked like over watering to me, use a soiless mix next time around, TRUST ME, You will thank me later. Get a moisture, PH, and Lumens tester, you will find them at any nursery, hydro store, home depot.

This will take the guess work out of watering them, remember the root system does not want to be drowned in water. This is why soiless mix is so great. Get some. Good luck.
