Can't get this plant out of stress mode. Its the only plant that took this route so far. I have 7 other plants and none has done this. I used Cal Mag, Big Bloom and Grow Big and the leaves are still coming out stressed. Its been in stress mode for 3 weeks or more. Any help would be appreciated.

More info would be helpful. Lights, temp humidity, feed etc.
Since you have 7 other plants that are ok, I’ll assume your lights/temp/rH is fine.
Those twisted tacos are amazing. I’ve never seen such tight taco leaves. Since it’s probably not an issue from the environment, it has to be an issue at the roots.
Most Likely Causes
- Genetic sensitivity or mutation
- Root damage or poor drainage
- Salt buildup or pH lockout
- Micronutrient imbalance (zinc, boron, copper, etc.)
What you need to Do
- Flush with pH-balanced water + light Cal-Mag (¼ strength).
- Check runoff EC and pH (target: 0.8–1.2 EC, pH 6.2–6.5 for soil or 5.8–6.0 for coco).
- Monitor new growth—if still twisted after reset, it’s likely genetic.
More info from you will help us to help you

I had them under 4 - 200 watt LED lights at approximately 3 to 3 1/2 feet from plants. I down graded to two after I saw the stress. Heat average is 77-79°. PH is around 6.2, humidity ranges from 53 - 65%. I checked my run off at last feeding, PPM- 649 CM- 1380. I'm using Fox Farm soil, so I didn't think a flush would be necessary. It was the tallest plant at the time of stress that's why I'm leaning towards heat stress. I took it out of the tent for a couple of days to try to relieve some stress. Put it back in with 2- 200 watt LED's and it hasn't recovered. Maybe I'll take it out for a week to see if that helps.

I would move the plant so that it isn't in the hot spot of the light first of all. It could be genetic but I'm thinking it's more light burn than anything else.
Do you have a way of measuring how much light is hitting your plants? Free light meter app will get you in the neighborhood. Android/Tent Buddy. Iphone/Photone.
I like to use DLI as my lighting guide to keep from light stressing my plants.

My lighting set up is not directly over the stressed plant. It wasn't directly over it from the beginning. But I did have my lights about 12" from the plants when all 4 was on. I extended my tent upwards another 3' and moved my lights up around 3-3 1/2 ft from the plants. Not to long after I made the move, the plant suffered stress. The ones directly under the lights did not stress.

5600 lux is about 120 PPFD and that is not enough light to burn a seedling, neither is 2.5 DLI. I admit you have taken canoeing to a level I have never seen but I would be very surprised if those lights were strong enough to burn anything. What is the temp in there? Get one of the light meter apps that RootsRuler mentioned and a wattage meter. I would be surprised if all 4 of those lights on single outlet are drawing 2000 Watts combined. What brand and size are they
I would cut those leaves off, dry them and use them for rolling papers
FYI When comparing PPFD vs lux, it’s important to recognize that these metrics serve different purposes. While lux measures the brightness of light as perceived by humans, PPFD quantifies the number of photons within the photosynthetically active radiation (PAR) range that plants can absorb.

Hmmmm.... with the extra info I'm starting to think this is genetic or some sort of root issue.

If you look close it looks like some of the damaged leaves are below healthy ones. Could it be something like bugs at the stem level? That's the craziest looking light stress.damage I've seen.
