I agree with
@MiPotFarm, those look like lower leaves on the outside edge of you tent. When that door is closed they're gonna be even more covered by the canopy above. Lower leaves will claw like that if they dont get enough light. If it was heat stress, they would curl the other direction. The only other thing it might be is mild wind burn, but I didnt see any fans in any of your pictures so i dont think that's it. I wouldn't worry about it too much, those leaves are gonna be the first to yellow and fall off anyways. Good luck!
