Okay, so here i am 3 weeks from starting my beans.
Lately their leaves look like under attack.

I'm thinking beetles, but i can't find any, and there's only one hole.
The main damage is on the side of the leaves and is basically carving them. Also some long ~3mm "trenches" in one leaf (not present at the time of the picture).
Other things I'm considering are...
-bacteria or other invisible villains
So, what do you think I'm dealing with ?
