Could be a couple of issues. I see some damage around the edge of leaves, which could be some burns from excessive fertilizing. The holes in the middle of the leaves seem like insect damage, perhaps earwigs? Earwigs tend to show up when conditions are overly damp and there is some leaf debris and other cover around. Is that the case perhaps?
After thinking some more, if this were partly earwig damage, I'd expect to see some spots of oily-looking black honeydew somewhere on the leaves. I don't see that.
Looks like it could be something fungal -- leaf spot, anthracnose, etc. Someone smarter and more experienced than me in this forum (which probably is most) can give you a better read.
Looks like a little snail damage in the first pic, but not enough to be troublesome.
The rest, to me, just looks like normal wear & tear from being in the outdoors.
Your youngest leaves look green & healthy.
Overall, your plant looks healthy enough at this stage.
