bag seed, day 14, leaves curling? [pics provided]

126w warm CFL..

no nutes, regular soil.. was planning on transplanting come 1st week of july.. for a day or two though some of the root was exposed, stupid me decided to grow them in a frosty clear container.. but i covered up the container to give the roots some privacy as soon as i got done talking to Italiano in my "2nd Grow Log" thread (indoor section), but come the next morning checkup i notice the leaves are curling.. also a burn on the tip of the leaf? sounded to me like it was a nute burn, but i've had this baby in plain soil i got from walmart.. no miraclegrow, no nuffin.. pics provided, anyone know other reasons why this would happen? i also gave the kid a extra layer of soil for provided support, as it and the others stretched about 3 inches from the cot to the soil, one of the kids began to fall over from lack of support, so i tied it to a stick.. whats the problem doc!?

pic 1 - plant C - the injured!
pic 2 - the crop of 4
pic 3 - plant B - beginning to fold upwards toward light?? why? you can see the change in the healthy green too..
pic 4 - oldest child, that burn on the tip was from the light falling on it once upon a time.. but seems healthy!
pic 5 - plant A - healthy!

why are plants B and C tweakin so hard? all have been grown under the same basic conditions

My guess that its from temperature problems.

Although the CFL's are a little too far away (indicated by the stretch), there might be too much heat inisde your grow box. Aluminum foil is frowned upon because of the possibility of creating "hot spots" on the leaves.

I would try to get some nice intake/exhaust to get that heat moving out of that box, otherwise, just lose the box.

IMO
:stoned:

My guess would be heat stress too.

Aluminum foil = Big no no
