You have nutrition burn badly and possibly light is too close. Yes about 83 degrees f is ideal for warmth. I suspect you have a ph issue. Have you calibrated your ph tool recently. I recal mine twice a week at least. Your ph should be 6.3 for ideal ph. Also watch your TDS as you go week to week. Will help avoid nutrition burn in future grows. Good luck and happy growing

Is the leaf is yellowing as well? If it is, it looks like you have light burn. Heat stress will cause your leaves to claw. You're lights might be to close, pull them up higher.

Heat stress will taco, that looks like nutrient burn or a cal-mag deficiency. But your temperatures are really high without Co2 being provided. Try to get the temp down or supply Co2. That could also be from light burn too if the plants are to close. Light burn and heat burn are different. Look up some great information on growweedeasy.com
