brown leaves

[dubele]

On to new problems....Within a day, my zucchini and cucumber leaves have brown around the edges of the leaves. I also have one leaf on the zucchini that is brown in the middle with yellow around the brown.

Any ideas on what is going on?

P.S. - Some of the pole beans have the same issue.

We should start with a little more information. Soil condition, fertilizer regiment, weather conditions, and watering habit. or a link to your other problems.
