looks like you burnt the fuck out of them. a couple look clawed (nitrogen toxicity) and then burnt. Possible underwater/heat issues also by how some of them are cupped (i think that's what it is called).
You will get much better info if you at least state your environment (lights and temp mainly)/nutrients/media

Light: 1000 hps
Temp : 28C, 45% RH
GH tripple set nutrient
Soil medium, promix HP
Water when top soil dry out

promix containers like to go from wet to damp - what kind of pots do you have it in? do you have any full pictures of the plant?
It is very likely you have been underwatering and burning them. more pics always help
82F is in the acceptable range, but i personally wouldn't go above that temp during flowering.
I think i read with a [higher temp + higher rh%, and vice versa lower temp + lower RH%] they do better, but i can't remember where i read that or if it's true.

No yellow tips, leaf fading from green to pale yellow. N deficiency. Late stage N def looks almost exactly like too much N. If you've cut back food N, P,K and everything else because your in flower then your doing it wrong in my opinion. But..... That is however a very different argument. Feed your plants or harvest crap. Your choice but your yield will be affected big time either way. Good luck

do you think it's kind of weird that the yellowing is more from the center up and not the bottom up like normal N def?

i know you say you water whenever the top feels dry, but promix dries out extremely fast, especially in fabric pots. i have to water mine every day, but it's in a 2 gallon. how long does it take for your top to get dry? promix also isn't supposed to look completely dry like that on top, it should go from wet to damp to wet to damp, etc...
do you feed every watering, and what amounts?

It is just the way that it's affecting your plant. I may be wrong however, too much N causes clawing, so does too little. Those leaves are shriveled and clawed up pretty good also. It's still a deficiency in my opinion. If your soil isn't amended much or at all and your not feeding any or very little then yes I believe it's deficient

Yes. Some water should come out the bottom regardless. Not like a river but definitely enough to know that everything is equally moist top to bottom side to side ect. **** If your growing substrate is peat based and dried out it will have the same nutritional value as shredded plastic

Maybe he is feeding a pure bloom schedule, which cuts out N too early? I see what you've said about no tip burn, which makes sense.
I feed every 2 days, the soil not dry out much...i wait till inch top soil dry to watwr
It happens before flowering, the leaves pale green and keep yellowing and dry
