In a word, yes. Leaves should be a healthy green and when they are not, they are indicating a problem. It could be a disease, but more likely it is a nutritional problem. If they are not wilted, they probably have enough water. They are probably running short of one or more nutrients or trace nutrients. Here is some basic nutrient deficiencies information.

Thanks for the help. I watered in blood meal about a week ago and they might look a little better. I am getting baby beans so keep your fingers crossed.
