Curling and drooping... Please help

Hey guys,

I got 12 babies under 2 1000w hps lamps in 5g pots, 707 soil and using the fox farm trio. Flipped to 12/12 8 days ago. About 3 days ago they got pretty dry so I have them plenty of clean water. Most leaves are taco curling under, drooping and tips are pointing down. Please help me if anyone has had this same issue and solved it.

Thanks guys!

pic would be a great idea so ppl can see what the problem is
as thay say picture make a thousand words and a video makes a thousand pictures

heat stress? maybe your babies are losing moister

Attempting to post pics for the first time. Not sure if its heat stress. lights are about 2 foot above and it stays generally cool at the canopy.

Heat stress is what it looks like to me. How's the airflow in there? Also how long ago did you water them?

What's your temps and rh, night and day?

Looks like heat stress as Caher says
