You may be experiencing the dreaded damping off, don't know, you provided no pix, just a guess on my part. If your using some type of medium that you have placed your sprouted seeds, it should be sterilized in the microwave, 10/12 minutes with lid on top for about a gallon, not tight, just sitting on top with your medium dampened so condensation will form on the sides and top. Will be very hot, let cool.
its all good man thanks for the advise i found out today i had a bug eating my roots there for killing the plants there in recover now got some stuff that will kill them now have to feed them with some root nutes and dose them again with the stuff i got and should be fine i hope !
Unlike humans seedlings can go for at least a month before any nutes are required, stop waisting your time, and study some more, germinating is an art, something you gotta do well to grow a plant Marijuana: Jorge's RX http://books.google.com/books?id=WRNNS2TUB3YC&printsec=frontcover&dq=related:ISBN1878823272
Whats wrong with it is it's an autoflower. Seriously though it was probably overfed or like mmman said it could be damping off. Either way you can't fix it if it's dead. Just plant some more, hopefully not autos. Grow weed like a man, kill the men that try to interfere with your ladies.
