First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?

Hey - hope all is well.. looks to me as if they’re needing a good feed of N nitrogen, they seem a bit pale yellowish. Or double check your PH run off to see if ph isn’t fluctuating. 6.3/6.5 at your stage, high humidy is your best bet to go for my veg tent sits comfy at 60/75 humidity and 23/25 temps using LEDs bump up temps and humidity you’ll be fine 💪🏻

Stop pulling off leaves till you have the problem solved. From the one spot I see and color of plant it looks like nutrition issues. Or if in coco a ph issue. Limited information makes it hard to properly assist.
