Help! Our tomato plants are having issues. Please help us to diagnose (we have a guess) and treat this. We do not use any chemicals and only want organic solutions, please. The plants effected are Juliets, Roma, cherry and large (can't remember variety) and we planted them in early June. Some leaves were turning brown and crinkly but now it has spread and the leaves have these spots and are not full plants. We are getting some tomatoes but not a lot. We live in Middletown, MD. Thank you very much for your help and expertise!!
From your photo the tomato foliage looks like it was subject to septoria leaf spot. This can be a common leaf spot disease of tomatoes and is favored by wet weather. See our website for more information and management http://extension.umd.edu/learn/septoria-leaf-spot-tomatoes
