Where did you get the seeds from were they store bought or saved? To me it doesn't look like anything is eating them it looks more like a mosaic virus. I will say that sometimes when aphids suck the juices out of plants they cause deformed leaves, but I don't think that is the cause. If other people on here think it could be a mosaic virus as well I would destroy those plants and start over. Typically there is discoloration associated with mosaic viruses so maybe that isn't what it is. Sometimes seedlings just have a few deformed leaves initially and then they seem to correct the problem somehow. I have let such plants grow only to be very disappointed with them. Whatever the cause those are examples of plants I would thin out.

Ah, thanks for your help Jeanne. I think that I may have found something else it could be. Thanks to your suggestions, I did a little more searching and found this. I just haven't found photos of any of these that have multiple stalks from one base at the ground, but definitely the same leaves. Here is a link that might be useful:

My Kentucky wonder pole seeds are white. If you cut the bean in cross section, it is round for KW. They grow pretty staight but not very long, nothing like Fortex or some of the other beans. They seem pretty resistant to heat and do pretty well here in the summer. I think I tried Blue lake once and found it stringy, the cross section was oval instead of round if I remember right? and the seeds were dark. Maybe someone else can confirm.

What you are seeing is probably fungus gnat larvae. Placing a mosquito dunk in your watering can will get rid of them. I've also heard placing bay leaves in the containers works. Spidermites like sundews and pings so keep them away from where the MG was.
