Do you have a fan near this plant?
To me, it looks like wind burn. Check this out: https://www.growweedeasy.com/cannabis-plant-problems/wind-burn
Just move fan away and give it a couple of days she will recover.
That could just be the plant. Light stress looks different. I have a gelato that looked like that and now it’s 2 weeks into flower and I still have these rando big fat spiky fan leaves
