Possible wind burn

Greetings everyone.
longtime dwc grower having an issue I never had before and I assumed it was due to windburn but would love some advice from my fellow rollitup family .
Im two weeks into flowering on a sky Walker lush plant. Ph is in range so is ppm . Only difference is that today the temp jumped up to upper 90s so to combat that I rearranged my plants and added a fan. I have my plants dark period during the day . The first photo is at 12 am last night the plant(the one on the far left under the led) looked healthy other then the top fan leaves slightly going upward . I rearranged them added a fan and shut the lights off at 9 am. When I came home around 9 pm the plants top leave got super skinny and twisted all ways around. The second and third photo of it within 12 hours . Since the only change was adding a fan I assume that’s the issue but could be wrong. Looking for advice on what it could be and how I could fix it if possible so it won’t affect yields

This looks like text book wind burn...Point your fan up... they likely won't fully recover. 2 weeks into flower, they may make a few more leafs, but veg time is coming to a close.

Most likely wind burn as mentioned but did you do a really good check for bugs? That's the only other thing I can think of to stun the plant that much, that quickly as well. Never hurts to double check and I'm sure you did.

Looks like this?

Thanks for the quick reply you guys def confirmed my suspicions… I pretty much figured that as well because I have my tent pretty much zoned in to a good environment no bugs good circulation along with temps so me adding a new fan to my system was the only new thing I did (huge mistake ) was just worried that it would get to hot in there
While I was gone(even though it didn’t) I actually had the fan pointing up on low but since then I removed it . As for reveging im
Not going to attempt that because the budsites are too far along. Was just wondering how much this would affect my yield
