Just trying to catch any issues as early as possible. Frisian Dew, outdoors, so there are plenty of options.

Anyone who can help pinpoint what might be causing this and how to prevent it?

Look on the undersides of the leaves for larvae, & get lots of sticky strips.

I couldn't seem to find any larvae or insects. On one of my other plants (That also shows symptoms) I found 2 egg sacs, you know like a spider egg sac. I have no idea if that's related or not to the issues.

Which particular sticky strip should I go for? I know there are different variants and I thought they were mostly focused on thrips and other flying buggers.

I've sprayed the whole thing with pyrethrum (Natural insecticide) and added Diamataceous earth powder to the top of the soil as a barrier. But I'm open to more options to get to the bottom of this :)

Edit: I found some sticky tape, that you'd wrap around your pots, to catch all creepy crawlies, is that the kind you mean?

My vote is thrips!

Maybe. I just had thrips last year and they didn't really make holes in the leaves like that, they more seemed to make marks on the leaves.

Like this:

But I'm buying traps that will also catch thrips and a few other sprays etc that also work on thrips, so I hope I can get rid of any and all pests... Knock on wood

Edit: You're right the first picture does look like thrips. I was too focused on the holes in the leaves. It might be a wombo combo of thrips and some caterpillar or perhaps thrips do make holes in leaves?
