Bean plants very yellow
I've never grown beans before, so I planted a bunch of different kinds of beans... most are pole beans. They just started comming up and now some are 3-4 inches tall, some are smaller, but I'm noticing that some of them are very very yellow. Does this mean that we're talking about some kind of soil defficiency? or some disease? Or are some bean plants like that? I mean it could be a nitrogen defficiency, that soil where they're planted is pretty crappy, but I thought that beans can get nitrogen from the air. Anyway, I sure hope they do ok, because I've never done this before.
