Yellowing leaves on bush beans
We bought the Victory Garden vegetable seedlings offered by the Thornton's Garden in a Box program. All seedlings are in the same soil with the same sunlight exposure (no southern exposure, a bit of eastern exposure, and a lot of western exposure but with a screen that cuts down this exposure). At first all plants showed some yellowing on the lower leaves. Worm castings cured all but now the bush beans have spotty yellow on many leaves. What is missing here?

A picture would be incredibly helpful in identifying the problem. Spotty yellow can mean so many different things.
Can you also provide us with how you are watering, and any other management practices beyond adding the worm castings you've done?
