Help! Leaf tissue deterioration on otherwise healthy plants!

Hello everyone,

I am in Day 4 of Bloom - I noticed some strange holes appearing on the leaf tissue on some of my girls here. The holes are pretty severe on one plant in particular, but I’ve noticed the same symptoms on some other plants of the same cultivar. The overall health of the plants is pretty good and new growth is pretty vigorous. I have looked closely with a jeweller loupe but can’t seem to see any pests around the damaged tissue.
Feed EC: 2.0
Room Temp: 84
RH: 69%
CO2: 1300
PPFD: 700
Growing in rockwool drip fed drain to waste.

I can’t seem to figure out what the issue is. No burnt tips or signs of stress otherwise - could it just be a genetic issue?

Any help would be greatly appreciated!
