corkscrewing leaves what the hell???? very confusing

Just brought 4 plants into flower leaves are twisting and corkscrewing, also growing shoots dieing raised light and ph is fine still looking for a solution would be most grateful

I've seen this 1 before can visualize it easily without a pic
What kind of dirt or grow medium, nutrients you're using?
I'm just going to take a guess thinking your underfeeding?
Low ppm's? Is this a possibility? A pic would still help!

Some strains just dp that, do they look bad? Post a pic

Root system issue, repot or reduce watering.

anytime this has happened to me its PH swings everytime, check your meter it might need to be calibrated

I do deep water culture hydroponics the only thing I have changed was cutting the flowering nutes in half because the plants before were getting burned

ph can be a issue in dwc, large ph swings can cause wierd looking twisted leafs, if to much nutes was a factor you would get the (claw)

the same thing is happening to me right now but I grow in soil. 2 of my strawberry cough plants, my other strains are ok

Doent matter soil or hydro ph swing still do the same thing

Sound like ph problems mate. You say your ph is right. What is it and is it stable or or are you constantly changing your ph?

don't forget heat stress and an uneven light schedule can cause twisted growth ...i've had that a time or two. It corrected itself a few days after it maintained a consistant light cycle.
EDIT.
didn't read the last part that your new shoots are dying... sounds like a salt buildup and/or heat stress. probably time to FLLLUUUUSSSHHHH.
