Looks kinda light light stress and high heat maybe how far is your light from your plant can you keep you hand right above the canopy comfortably for a couple min? If not its probably too hot for you plants too. Do you have fans blowing? Maybe some hot spots are forming

What have you been feeding? How much? How often?

First glance looks like a heat/nute/ph issue.
How hot is your room? You have leaf curl.
What do you feed with, how often and ppm?
What medium do you grow in? What's your ph?

Idk how it could be heat stress the room temp is like 65 before the light turns on light distance was 18" @ 600 watts now I set it to about 22" @ 450 watts. Plants are week 4 of flower in 3 days. 660 ppm, Flora Nova Bloom, & Cal mag Plus. Bubbleponics. The leaves were just turning pale, like light green then boom man, came in this morning. Ph is 6.0 set it at 5.8 and let it rise to 6.1. Been cycling water weekly. I raised lights to 24" and dimmed to 50% 300w but I don't want a lot of stretching.

you could have some light burn maybe but I can say with certainty you have magnesium def or magnesium lockout
even the healthy plant in the back is showing mild signs
the one closest to the light is showing it first because its more amped up from the high lumesn so itll show first
and it might be a plant that requires more nutes than the other
we need to know what your feeding to determine if your low on magnesium or high on calcium or potassium which can lock out magnesium
(zinc... no your not having any issues with zinc)

Flora nova bloom @ 7.5 ml per 4 gallons with 1.5 ml of cal mag plus, normally I'd be running other adds and a different base but I ran out and literally the only thing any place had was ace and it was the flora nova line. My nutrients are suppose to be here tamaro. Ph 6.0 ppms are 660 it's at like 24" now and it's still not stopping the advance of yellowing.

Thank you I just changed my Rez and did 8 the plants are starting to look a little better but I think that every night for the past couple days and I wake up and it's worse. I ph to 5.8 and dropped the cal mag as well. After the leaf becomes that pale will it regenerate or is it just better to cut off necrotic tissue to help the plant recover?

if you stick with the flora nova
because it so high in P
when you get a chance
get some battery acid from the auto parts store for $10
fill an empty 1 gallon jug half way with plain water
add the pint of acid and then top off until full with more plain water
if you cut it with water itll be easier to work with and closer to the strength of the ph down (phospric acid) your using
youll save some money too
the phosphoric acid adds more P and you don't need it
