Something going wrong here...

Yo guys... re-potted my plant the other day with this miracle grow potting mix compost and i noticed yesterday that one of the leaves at the bottom of the stem started going yellow... got back tonight and it's even more yellow and it's drooping alot more... It's got water and it was in the sun today and was fine but i out it under four 20w cfls for like 6 hours n it's looking like this...

cud the fact that i'm not giving it any dark time be a factor?
I thought 24 hours light was fine in the vege stage...

Or maybe they don't like the compost?

Please help...

thats not a leaf, its a cotyledon. they're only used by the plant for feeding before the roots are established, let em fall off, clip em off, cast a magical spell on them to fall off, it dont matter.

Your safe those die ,sepals they always show after they sprout along with the two true leaves.KEEP SMOKE ALIVE!!

he he he he he he..you're funny..your good dude..leave it outside instead of using the cfls if you can.

Oh thank you... thankyou so much i was well worried...
I was about to get well angry lol and my internet jus spazed out for like two hours... well annoying.

But thankyou guys.
