Hello. I am starting to see my tomato plant leaves change color from green to a brownish rust color. Any idea what is causing this? The plants have been very healthy and productive all summer, but now are beginning to show this color change. Should I be concerned? If so, what is the appropriate treatment. Thank you for your help.
