Worst Ever Fall Bean Crop

[Zone9b]

A little more info on my bean problem. First I would like to comment to the root condition of two of the varieties. I pulled some Provider plants and they didn't really have many roots. Then I pulled some Jade II and there roots were in fine condition. I had inoculated all the bean seeds I planted.
The Jade II roots were full of the nodules one would hope to see. I guessing what ever my problem is it isn't affecting the roots.
However, one of the things that all the varieties have in common is very poor bean production.
The first 2 pictures are from my Rattlesnake pole beans.
The next picture is of Rattlesnake beans which look more or less normal.
The final picture is of Provider beans which have a large purple/brownish spot on the
sides.
