Guess what baby you fert burned it.
Is that MG soil or fertilizer?
Your humidity gets to 100% at night?

okay... well at least it was something stupid that i did. but yeah it is MG ferts not soil i use soiless mixture and mix my own peat moss, vermiculite, and perlite. i found it to be pretty good. and yeah the grow room looks like a rave party with all the smoke when i turn on the lights. also i didnt know that nute burn would make them all thwist upward and turn that whiteish color? but thanks for the help

Well since you are feeding it it is probably not deficient in anything.
Try a soil flush to get rid of the excess nutes. Your soil less mixture could be troublesome too because soil-less mixtures should be at pH 5.2-5.8 I would think.
