Brand New Grower...want some second opinions...

So I have read up on a bunch of info I found all over the internet and the forums, and info site after info site. So I figured I would let experienced folk give me some insight on whats going on here...

My guess is I over-nuted...(yea i know...what else is new) - just like all the other eager noobs I jumped on the same boat.

Here are some pics...the last pic was taken the same day I last fed it...as u can see it looks fine and perky and healthy...

the first 3 pics however, were taken about 3 days after the last feed...any guesses?

I have it under T8 flouros, 18/6 light sched. - scotts premium potting soil (.07 .01 .03) - in a 6" pot...used MG all purpose liquid plant food (12-4-...temp remains around 80-85ºF with the lights on...

I flushed it once i saw the burn spreading...the next day it was still worse so I transplanted it into a fresh pot with dryer soil...does it look like she will make it? I could really use some expertise...thanks a bunch in advance for any input and for your time.

P.S. - I apologize in advance for any stupid questions that I might ask!

its gotta be nute burn the soil your using has nutes in it so when you added more soil it added more nutes try flushing it with ph balanced water let it dry nice and good then use water a couple more times before giving it nutes make sure you let the soil dry between waterings

that doesnt look too bad... flush it out well and give it time to dry out and recover you should be fine

your also to wet. the down curl means she has to much water inside her and isnt processing any foods right. and the soil has food so each time you water its releasing more then adding more on top. on your way to a lock up.
the first shot shows me environment issues as well. the tops are cupped up from heat or humidity then lower has down cup. i see a side twist form ph usualy meaning it aint eating what your giving it and dropping ph. fix the room and the rest will fall into place. to hot and whats the humidity. try n get down to 77 degree, that temp is ok for running co2 but a tad warm for not. and make sure to let that soil dry right to the bottom drain holes each time
