Oh no! Have you turned the lights down? Just wondering if that would let the plants have a day or two to recover from dehydration.
I did a quick test on the worst plant in the back last night from a cutting I took the day after it happened and we are only at 10% THC (the DJ ShortFloxChemdawg). The PCK to the front tested at 17%. Not great but we will see what happens. The mother on those PCK clones tested at 20% when fully finished.
