can someone take a look

i have 14 lr#2s under cfls and a 150 hps.yesterday they looked fine --this morning i got up to find 1 fem getting sick--any idea what caused this.in soil--no way to regulate heat---in a storage building--all the rest look great---this is a fem cronic lowryder so i want to get her well soon.i brought in house ,put under a cfl and set her on a heat pad on low!!

How cold is it in the storage area? Just keep an eye on her, she'll recover. But what about the rest of them? I wouldn't let it get down past 50 for too long.

would a tent help keep plants warmer---with lights and a fan curculating the warm air--or no?

Yeah, I'd say it would help. Also, make sure the pots are up off the floor. The HPS will be the main source of heat, can you not put a small ceramic heater in there if you tent them?

How often do you water the plant? Did you recently do a transplant? Looks like you have a container inside a container? It looks over watered maybe.

i have container without bottom sitting in one with bottom after sprout i just sit in a larger pot without transplanting,just remove the pot with bottom so soil shows and sit in larger pot<normally i plant outside.>i have 13 more with this one and all look great except her.she looks wet because i gave her some charged water<bubbled over night>just to see if it would help her.i also set her on a heat pad on low and under 1 cfl at 2 inches to see if she responds
