Bean question
 

Here are some beans I'm growing:

The beans on the left are for the most part doing quite well, where the ones
on the right have the wrikly leaves and are not as robust. The ones on the
left are blue lake stringless, which I've grown for years, they grow well.
The ones on the right are chinese noodle beans from rareseeds. My guess is
the ones on the right have not been bred for disease resistance, etc.. Or,
they just don't like my particular climate. Are there any diseases of beans
that can do this?
