Hello there! Are you still on 24h light?
Also how far the canopy from light?
Many times when plant is stressed this happens light bleach, maybe cut to 20h light and higher up or dim down the leds?
Anyway i would not worry too much because she us still healthy and when plant in flower it is demanding time so often this happens. Good luck
@Eauderay, I've played with the light schedules this run probably too much but I also added some monkey nutrients pk additive that I think has caused the leaf issues as its happened to all my girls, not using it on this next run to see the difference.
