I've been growing tomatoe's in my greenhouse since October and have noted that the leaves on the plants have been curling up and are spotted. Once that happens, the leaf dies off. New leaves are still being produced. I've notice that the leaves have small weblike growth on them. I was thinking that I might hava mite infestation. I'm also growing cucumbers, lettuce and have a lemon tree in the greenhouse Pics can be seen at:
