What is your soil PH?

I don't know the soil ph but I only feed 6.3 ph water and my dwc is 6.0 ph water

Oh yeah? How come?

If some of the plants are in soil, it could be an issue with nutrient build up causing your soil-ph to be out of wack. I don't know that much about DWC growing in all honesty.

Just what I noticed the few times I've grown under LED's. They need more nutrients overall. A range of 50-70 ppm Mg per gallon is sufficient.

Ive been giving them a cap ful of cal mag everytime I water is it possible that it's got too much light? I have a 240 watt led qb about 22 inches there mostly in coast of maine super soil the only other thing it could be the temp or humidity it gets a little cold at night and dry I have a humidifier though idk it's so frustrating

You're probably right then. Try raising the light as much as possible and see how they respond then lower gradually. Cheers!

50-70 ppm per gallon is usually how many ml

Honestly as a resident of Maine, I've heard from a couple cultivators who use Coast of Maine that they have issues with PH. I have only used the Stonington blend before and I didn't really have a fantastic experience but nothing like this leaf twisting.

I lowered the light because there leaf temp weren't even 70 degrees

Don't heat the plants with the LED's. If you struggle with temps you need to add more heating or rearrange the circulation to exhaust out in the same room as the tent. .

Also, if all your PH readings are right but you're still having this issue after adjusting your LED height, maybe make sure your PH meter is calibrated correctly.

I think you need to fix the environment before to really know if it's a Mg issue or not.
LED's need a little more heat than regular HID because of its lack of infrared. While newer LED's has implemented infrared it's not comparable to HID's.

Ok I read it could be drastic temp or humidity dips also

It's weird though it's only happening to the plants I'm my closet

I mean realistically man if you're having drastic changes in your humidity and temp you need to focus more on your environmental control. It seems like every message you send reveals another possible reason for your plants stress. The reason we focus on environmental controls as cultivators is so that when our plants display anomalous behavior, we can check our environment for variances which may explain this issue.
Your problem right now is that you have quite a few plausible explanations for this plants stress, but very little idea which of these is actually causing the issues.

I'm just going over what I'm doing to try to spot what the problem could be it could be anything I mean my temps don't dip below 65 or above 76 the humidity is the problem it's winter in mass I have a flower tent and veg tent in my room so it's a little difficult trying to make sure theres not too much or too little humidity but I think we forget that plants grow outside fine and the weather outside is constantly changing especially in mass so it's possible it could be anything that's why Im asking if anyone else has had this problem
