Send into Shock

So i was wondering if changing the lighting schedule would send my plants into shock cuz i just switched to 12/12 and my leaves are starting to droop a lil bit. Is that alright?

Merely switching photoperiods shouldn't do that. This is likely a watering problem, either too much or too little.

Yeah, like ^ said . . . my guess is too much. Here's why.

I've been trying to water by schedule instead of actual need, and that ain't wise, but anyway, just put several into 12/12 . . . half are limp for first few days, until I guess my over-watering experiment dries up a bit. I see yellowing.

Won't try this again . . . seeing tip burn from same.
