Could be a few things light stress? Does it want different light cycle? Nutes? Air movement needs increase, how long till flower is done.? Can you push it that long? These are all questions I ask myself. I hope you can amend this quick! Good luck!

It's on 18-6 grow peaceful soil is pre amended with nutes lights are 28 inches from tops about 8 more weeks I was thinking it was because it got around 85 in the tent the other day but wasn't sure so made a post thanks for the response

My plants leafs get crispy late in flower. Sometimes lower leafs, earlier also.

I suspect its because I’m running these plants hard under LEDs with salt based nutes .

I’ve found that if I can keep temps under 80f during flower, my bud tastes much better. I’m thinking temps higher than 80 start to burn off all the good stuff

Studies at University level and from commercial growers has shown that high temps in flower above 75 degrees has a detrimental effect on Terps and potency.
The resin and tricomes store thc and terps in the plant. Terps and resins are volotile organic conpounds that can evaporate at low humidity AND higher heat.
It looks like heat stress but I would also be looking at humidity. Very low humidity and high heat over transpires the plant running water through it trying to protect its self.
Def look at all the guardrails you have in place. Check PH review any notes on watering has it slowed or quickened its water uptake.
Any plant in stress can benifit from a more slower heat range and lower vdp by adding humidity. The key is not to not overcomp the change. Heck even 3% raise in humidity at 85 lowers the rate.
How long did it take to get that bad? was it overnight or a week?
