Is that the one that's like $10 at home depot? If so they aren't accurate enough to grow well with. You also need to know what the pH of the water is as it goes into the container. The runoff test will help you determine what is going on inside your container. Read that thread, it's a good one.

edit: The plants don't look nearly as bad in the second set of pics, are those recent?
