Help! leaves are turning yellow and curling, first time grow and need help!

ok i've had this for only like 3 days and its a week old, it was growing really good till yesterday but i didnt really notice it that much till this morning. this is my first time growing and i wanna be able to continue on with this plant. i took acouple of pics of the plant and also of the bow im growing it in. please help anyone?

i also put some pics it looked like before

whats your setup? lights??

Have you fed/watered? If so, when? Just to be sure, that burned leaf is from the bulb, correct?

Replant into new pot with new soil / Pearlite. Don't nute...new soil has enough nutes to correct your problem to start.

Get more light on that plant.

first thing i got to say, you uploaded a hell of a lot of photos mannnnnn! haha. have you used any nutes on it? if not, what light are you using? could be burning the plant. without more info on nutes and lighting i dont no what else to suggest, apart from how much water your giving them?? GW
