Is is this Nutrient burn?

This started showing up a little over a week ago. So far I have given it ph water around 6.5 twice since without any added nutes. Was only using about half fox farm recommended nutes but did start adding some cal mag that does have some nitrogen in it. 2-0-0 I think. Was planning on switching to tiger bloom as I am now a week into flower cycle but don’t know if I should give them any nutrients when they need watered again

Gotta get some pics up in natural light & w/o the blurple on. She in fox farm soil too, ocean or happy :frog: maybe?

happy frog

Not nutrient burn but looks more like the start of potassium deficiency or could be start of lockout due to soil Ph being off…
Based on the pics above…subject to change

If this turns out to be potassium deficiency should i feed it immediately or wait until it needs water? I watered 2 days ago and they are still pretty moist. It usually takes about 4 days between each water

Will post pic with light off when light goes out at 6:00

This one near a fan? Looks like possible leaf rub. Had one outside and it was really windy for a few days, this was the result.
