This week I have moved this plant from the cupboard to a 4x4 tent with AT#1. Guess I didn't need to train it down so much. Probably needs a little defoliation.
Adding the bigger fan seems to have hardened leaves and stems a bit and it was looking decent after 2 days away.
I have the same lights and similar light distance, and I was in this exact scenario last week. Leaf drooping after increasing light intensity. After turning it down again, the leaves perked back up overnight. The only difference is I was using 18 6 lighting.
@mybuddymitch, thanks a lot this helped a lot. Now that I've switched to 12 12 light they look way better too I think they may have also needed a bit more airflow and and just a break from the light instead of 24 hours would probably have already been a better idea. But they are looking a fair bit happier today.
