Bite and 'tear' marks on fan leaves

I went to visit my guerilla site today to feed and check up on my 3 photos, when I looked closely I noticed dozens of what appear to be caterpillar or slug holes around on the plant, I had laid down slug pellets to counter this before I left, however the main reason for this post is that I'm struggling to identify the tiny little holes that are dotted around, mainly on the lower fan leaves. Also as you can see I have tears along the edges and the middle of some leaves along with some limited white/yellow spots in some places.
I have checked the underside of the leaves that were most affected and didn't notice any obvious critters.
Any replies would be much appreciated.

Maybe important to also mention we have had fairly heavy rainy and windy weather for the past few days. Everything that is seen on the plants has happened after the weather hit.
