folding leafs in veg cycle

[cashforgold]

I am growing 4 big bud plants in moisture control potting soil. They are about 7 weeks into the veg cycle. They are about 17 inches tall. One of the plants tho has leaves that are folding on the sides, almost drooping. I was wondering what this could mean. I am using a 90 watt LED light 630nm red 455 nm blue. Thanks for your help

One 90 watt LED for 4 Big Bud plants? Can you post pictures of you droopy plants. Much easier to diagnose with a photo.
