Holes in new leaf growth

Cheers guys have giving her a flush with ph water its bubba kush island and photo period and I'm using her for cutting so could of been abit rough maybe while topping but besides that's she looks lush

Wholes in new leaves are probably from being a little rough from previous training. More concerning is the magnesium deficiency that’s hitting your older leaves. That’s one deficiency you don’t want. But don’t rush to increase feed and end up with nutrient lock out. Coco is awesome but tends to have a hard time absorbing micro nutrients and if you let your PH ride to low, will end up with those defs for sure. Over watering is also notorious for causing this def. A PH of 6.0 is optimal for coco so if your roots are well established in their pots you can flush out with that PH and nutrients well suited for medium. Good luck and do chose a grower! Cheers 🍻

At a deeper look there appears to be an initial magnesium deficiency (bottom leaf discolored between the veins). Maybe some more experienced growmies can confirm. However, holes and distortions seem to be a genetic feature. All my plants at one point showed that

Hi, I think it's genetic issue, nothing to worry about, otherwise looking healty girl

Hi, You might have a bug hiding somewhere thats eating ur plants. Troubleshoot every single part of the plant, immobile nutrients, ph to low of high. Etc. Hopefully this works for you, Happy grow!!!🌱

Looks like it might have been damaged as small Growth. I'm not seeing signs of pests. I personally wouldn't think twice about it. Plant is healthy 👌. Happy Growing! 🤟😜

it's a slight deficiency bro... maybe the airflow is pulling in warm air and blowing it to that spot... maybe there's really intense airflow directed at that spot. 👆 Don't worry, but keep observing!
