really worried about this one

I have 4 plants, 2 that look pretty good, one that is tall but has far less growth than the rest that is pale and yellowish for the most part but my main concern as of right now is the last plant im about to discuss. This plant seemed to be doing pretty well, i just transplanted them all from a 5 inch organc coconut husk-type pot into 5 in net pots in a 24 gal tote, 4-4 in. airstones and a 950 gal/hr pump, the pH level appears to be correct (yellowish-green on the test kit). The plants were transplanted a wk ago, the day after the transplant i was gone for 3-4 days and when i returned i saw this issue. Using cornucopia plus x2 formula under a 400w HID, i just moved my light up about 12 more inches. The light is about 2 1/2 ft above the tallest plant top. There is also a oscillating fan blowing on them, keeping the temp about 80-84 most of the time.

The pic ain't real good with them hps lights!
It has burnt leaves tips and upward canoeing leaves?
It's burnt?

burning man lol

ur plant got cooked bro.

they did get burnt...but it looks like a nutrient burn, or a deficiency due to to much of something. kinda hard to tell...pic isnt great...i had the same problem with a plantin dirt...but it had no drainage, and couldnt breathe...thats why it got the curl...res. temps??

idk if the plant was too close to the light, or if its in shock from the transplant, nutrient burn/deficiency, but 2 of the other plants seem to be doing just fine..there are a few leaves between all of the plants where the tips seem to be burnt a lil but this plant, the leaves are twisting and shriveling, canoeing upward...is this plant going to recover? idk what to do :-/ im not sure the res temp, have to pick up a thermometer today but i have included 2 more pics to help find a solution. the roots dont appear to be taking as much action as the healthier plants. any help is greatly appreciated

I dont think its burnt, Quite the opposite its starving. You have severe root system issues(i think they are rotting) imo, or your ph is way out of whack, get a digital ph tester(not the test kit,not accurate enough) and make sure its 5.8. Im certain one or both of these are your prob.

bottom leaves do indicate she needs fed...idk though, your root system should be much healthier...brighter white...again, res. temps? how often do you add fresh water? i hear keeping res. temps can be a bitch...obviously you dont want a hot res.
