Help :(!!! my leaves r starting to look yellowish

i think its because i had the light to close, i had a 65 watt about 2inch away and my babys are only 8days old and 2inch tall, how could i save em

A pic is necessary in order to find out what the problem really is.

Yellowing could be because of: mineral or N/K/P deficinecy, heat, nute burn, wrong pH, wrong nutes etc etc etc...

Don't you know a picture is worth 1000 posts. (Saw this in someone's sig.)
