What is this on my bush beans???

[A. Simon]

Hi All, 

My bush beans are a little over a week old and the leaves seem to be shriveling and getting holes, although I see no bugs. Can anyone identify the issue and maybe even give me a solution?

Thanks in advance!!!!!

I'd go out at night with a light and shine for slugs/snails.  If inside, no clue.  If slugs, you may see some slime trails.  Good luck.

Thanks a ton, George. 

They are outside, I will check it tonight.

However, I didn't see any slime trails.

There are other nocturnal pests too, worms, beetles.  If you don't see anything during the day, it's probably happening at night.
