1 out of 7 looking bad, heat stroke?

Hello, I am currently growing wonder woman ak 48 and full moon in a cfl/hydro setup. The plants have been flowering for a week and a half now. Ph is 5.7 water temp 72-77 and nutes at 1800 ppm. When I switched from veg to flower the next day the full moon showed signs of over heating. I began foliar feeding and made sure the temps stayed low and over the previous week she began to recover, now she looks worse but all of the other plants look great. I am not sure if the full moon has different needs in flower as thru veg she was doing fine. What should I do, could I re-veg her and try to get her healthy? This is my first successful grow and I really have no idea what to do at this point any help would be greatly appreciated, thanks

the first picture is the plant in question the other is a shot of the healthy plants

I'd say don't foliar feed it any more ,,it will end up burning the leaves just like it seems to have done to your plant...also,,have you checked her for mites,,etc?? she looks a little like she has some bug problems....use a fan to keep it from getting too hot...good luck with that :^)

yea I have checked and dont see anything, have been spraying leaves with water as of yesterday instead of feed spray.

I would not spray them with any thing

now that ur in flowering def DONT spray the leaves with water or anything.. nice lookin plants on second pic

do u spray em during the day? only do it at night as it causes damage via water evapouration durin the day under the heat
