My pole bean leaves are curling and turning brown on the edges. What's up with this? I have looked for bugs (none I can see) and put on some extra Ironite. I live in the Austin area and have a two foot raised bed. I even put some Sevin Dust on them, but the problem still persists. What am I to do?

The plants are underwatered. Increase watering. If they are currently getting water, check for bugs on the roots that are restricting water.
