they should perk back up soon, although I took like ten clones off a plant once and didn't wait to put it into flowering... it's whole flowering was retarted... I got like 10 grams off the plant when I cut it down early... that's alot like what it looked like at first... but I fucked up with the nutrients that time too... too much sodium... ha ha
that was a while ago... but I would guess those plants are just stressed. raising the light slightly is a good idea, and make sure your room is welll ventilated and check your temps, especially soil temp.
if it doesn't perk back up, I would check it for prysithium or vusarium wilt; it's probably not though... watch the plant closely to make sure you don't start developing leaf spots, or any abnormalities...
I would think they should recover in the next week.
