Beginner Gardening: Brown dry patches on Bush Bean leaves, 1 by Kindlekat

I went back and read the topic that dealt with this already, but everyone had said their new leaves were fine and in the end their plants were alright, but no one knew a cause. Well I have the same problem this year. I've never grown beans before, but hearing how easy they are made me want to try, so I planted some yellow pencil wax and blue lake bush in one of my ebuckets. Some of the first leaves had brown patches, but now there are more sets of true leaves up, and they have brown patches too! No pests in sight, and I haven't over fertilized because I haven't fertilized at all. Watering is even every day due to the self-watering ebucket they are in. What could be causing this, and do you think these will still produce beans?
