Plants curling upwards and some twisting 2 weels old

Hi I'm new to this and a few days ago my plants looked great but now look like they are curling up and some of the leaves are twisting was wondering if this is a overwatering problem

.

Bpk do you know your ph & temp?

.

It's a lil high like 6.9 also been dealing with a bit of a heatwave and the last few days been tough to keep my temp under 90 during the day

That's the ph of my water anyways I dont have a soil tester yet

Heat stress, what light you using ? And distance?

1200w led about 2 feet above them

.

I would flush them with clear ph'd water then when they start to dry repot them in 6 inch pots.

Easy on the Nutes after that, for awhile.

.

Is your light 1200 watts from the wall or 1200 LED watts? Check the label on the back of the light.

If it is 1200 true watts you'll need to back it off the plants.

.

Ya its 1200 led watts I think it's like 600 something from the wall. I ph'd my water to 6.5 last night and flushed them out and was planning on repotting them. I havent given them any nutes yet, should I start once they look less stressed?

.

Transplant when the root ball dries and pulls away from the pot walls. Be sure to Ph the water that you use to wet the new soil for the new pots.

Add light nutes the watering after the transplant.

.

Repotted them all today after a couple days with proper ph water they all had good looking roots and are looking much healthier after the better water

Looks like they are really liking the new pots day 20 and looking great thanks for the help everyone
