This problem started with the cucumber plants only, but I am now seeing it start to spread to other plants as well. Even those that are still really small like pepper plants and a couple watermelon recent sprouts I threw in very late. The following link will take you to a photobucket album with 11 pics of the different plants. This is my first year with a garden. A project my kids wanted to take on as a family this year. If anyone could tell what this is and how to treat it before I'm at total loss I would appreciate it.
