Did I Kill Her?? Plz Help

ok for those who don't know,

2x 32gal rubbermaids (my frow box)
7x 27w CFLs on 2x Bathroom fixtures.
120 mm fan for exhust
Scotts Soil 4-5g POTS
3 bag seeds

Ok germinated then planted. 1 out of the 3 grew twice as fast. in one week the roots were through the drain holes. so that one plant i transplanted into a 2 lt bottle. which i black taped the sides to light can't get through and cut holes the bottom for drainage. ok heres the problem

the one plant i transplanted i think i transplanted to soon. the round leafs on the very bottom look fine. the next leaves up (Large single bladed leafe both ways) jsut over night grew 50 of that leafs leaf is yellow and some brown. i an slowly she is welting. i also think i overwaterd so only thing i think i can do is let her dry out for a week or more. anything you guys think i should do to help her?

no Digi to take pics

the other 2 are looking fine. the are both about 10-11 days old. how long until i transplant them. cuz they to have multipule roots trying to come out of the holes. are they fine or give it another week and when i decide to start ading nutes transplant then?

its probably nothing too serious, just let it dry out, dont add any nutes! not until they are at least a foot tall, seriously, it wont do any good whatsoever, and when you do, do it gradually... good luck
