I 2nd the advice above. You said you came back to the plant looking like that with a pH of 7. I would get your pH on track, wait a few days, and those girlies will be back to their strong selves. You have recently cut into the plant, changed the lights on it, and neglected it for the time being. Just in my experience, the more you stress a plant, the harder it is to bring it back. I'm sure you've already corrected the pH and adjusted ppms and all that. So if you were to take clones now, it might be ok, but whats a few days?
