What is this def.

Is this a def of a ph issue.

Growing in promix with gh nutes.

I've only given her 1 dose of cal and mag a few weeks back but this doesn't seem like a cal or mag issue. At least not to me.
Maybe some weird light burn idk.
It's only on a few of the top and center leaves.
1000w ac hps about 14-18 inches awY in a 4x4. Its around 75f lights on 65f off and 40-50 rh. It's red widow 13 from dman seeds
Any help is appreciated.

Hello,

4-5 days ago leaves started doing an upward taco effect only in my veg. I have 3 wall fans, and a mini split to keep the room controlled. Temps are between 78-81 with 51-76% humidity


However, when I do sprays and waters etc... my shop is very cold and let’s a rush of cool I’m while I’m working in there


Here are some photos - the plants most affected are my chocolope the majority of my Keebler strain doing have tacoing like this going on and they’re all lumped together...
