I have been doing some research on why my plants have been getting these spots on the fringe of their leaves. What I have learned is that it may be happening from over watering. The picture shows that in the foreground there is a leaf that has suffered from this spot disease. This is Japanese Cucumber; I have noticed that most of my melons along with the cucs and tomatoes have these spots. My wife and I have seriously cut back on the watering and have noticed that our plants have really taken off. The picture shows a new leaf that is virtually spot free and strong this leaf grew after we cut back from the mad watering. All of my tomatoes have also shown great improvement as a result of cutting back on the watering. What we have done was to give a good watering every other day rather than every day. And with regards to the cucumbers we have literally gone to watering this girl once a week. As long as the soil stays moist and is not dry she seems to love the little neglect
