Can someone tell me what this is on my rattlesnake beans and how I might go about handling it?

It looks to me like something is wrong with the soil. The light green (yellow) color of the leaves isn't usual for that species. Weird colors in a plant's leaves are often due either to something toxic being in the soil, or to too much/little of an essential nutrient, or too much/little water, or the wrong pH, or any combination of these.

In cases like this, I find it easiest to start over with different soil.

Yikes! We got a bunch of this soil from the city. My parents are using it too. Several of the plants had stalled during a cold spell we got and several of the leaves turned yellow. Now everything seems to be improving with warmer temperatures. If it was something toxic wouldn't it be garden-wide since everything is planted in the same soil?

Everything in your garden might be suffering, and you might not notice if the whole garden were affected. I don't use materials from the city because of the totally non-vetted nature of the inputs to their system. I've seen too many ruined gardens in my neighborhood.

In any case, each species, each variety, and even each individual plant will have different susceptibility and growth requirements.

It looks like the beans are growing in a plastic tote. That's tough growing conditions for plants in general.

Is there some sort of test for the soil to find out if there are toxins in there?

Plant a few seeds of various species. If they end up yellow and spotted...
