What pest?

[Raindancer411]

Hi All, I came back to check my veg after a weekend away and found that the leaves were all contorted and had a hole in etc... Have put some pictures up... Was wondering what may have caused this? I had a check of the plant and cant see anything...

Doesn't look too bad to me. Couldn't be a touch of leaf miner could it? I wouldn't worry myself - but I don't worry much about me veg. They've got 2 chances!

Have they ever had aphids on them? I've seen similar effects on plants that have had aphids (even just a few tiny ones) on the developing leaf buds. When the leaves grow large they are left slightly distorted.

Nice healthly looking plants though
