leaf miner ?

[Bren In Pots]

I think my chilli plants have leaf miner there's channels between the leaves can't see any other damage no bugs or anything. I'll take a photo tomorrow when the lights better.

You can spray, but best earlier on to cut out the affected leaves.
It is very common on tomatoes.

My alpine strawbs have got them too, I just pick off the leaves where possible.

I got them on my tomatoes. I pinch maggot thingie between thumb and finger and leave the leaf where it is, with a squashed maggot inside. Some leaf better than no leaf, right?

I've had a look and can't see anything in the leaves just the tunnels they leave behind.
