I don’t know what kind of light you’re using and what the distance is but 80% on most modern LEDs is an awful lot of light unless you have really good amount of headroom. If you are getting bleaching at 100, I would not at all be surprised to see some stress that toasted some fans on one plant at 80. Doesn’t matter if they’re the same cultivar every plant from seed is a little different and has their own nuances. Some are more nutrient sensitive, more light sensitive, etc. Based on your pictures and description, that sure looks like the situation. I still probably wouldn’t do a thing about it though other than maybe not keep that one if you’re someone who clones plants to keep and run again. I have run hundreds of plants over the years. When you see damage that’s focused on the upper and exposed leaves, particularly when it comes with twisting and taco’ing, my money is on an overlit gal. I would keep an eye on her for throwing nanners from the stress. Other than that, it’s not that bad and she should finish fine.

not saying it’s your issue for your concern but raise your light 10 inches if you can,.. you can see the beginning of light stress,..
leaf edges curling upwards and yellowing tips with that the praying leaves are also a sign of light stress in this case,.
