Holes in leaves can't find bugs

Is there any chance that you have fans blowing directly at your plants? Honestly looking over your post again that is the only thing I can really attribute to that type of damage. There is also a hole in another leaf in the same region of the plant, it honestly appears like a vacuum swiped the plant and caught some leaves or maybe unique wind burn.

Not OP but I bought two oscillating fans a week before the last finish. Didn't think of these as a factor. They are a little stronger than my last ones. In a 4x8 I had 15w fans in each corner towards the plants. Never had any problems like this. But the fans were weak. Now I have raised the stronger, oscillating fans and see what happens.
Some marks look really weird like dipped in acid.
Thanks!

I have the exact same problem for the first time as well and its the first time growing in soil. Never had it before. Bugs were my first thought but I could not find any.
It looks like that the new leaves can't unfold. The folds are like glued together, this is where the hole appears.
Doesn't seem to have an effect other than the foliage is damaged.
Let's see how it goes!

Edit: it's also the first time I lowered my lights (led)

The increased light intensity also plays a role I believe.................

It's best to create airflow in the room overall vs blasting plants directly with fans. Should work out nicely for ya.

That's what I usually aim for. I have always negative pressure inside of the tent. Climate is alright. But I have changed some factors and never had fans blowing as strong as the new ones. It's a quick fix and I'm curious what happens because the damage looks like there are 100% snails inside the tent
