Q.Tomato leaves turning down
I have 2-5 gal. pails with 3 plants in each. I started these plants from cuttings from plants I had last year. The plants are now about 4′ tall and are flowering. At present I have 1 tomato. My problem is the leaves are turning inward. We live in Wilmington, NC. My plants are on the closed in back porch, which is where we have our hot tub. What is wrong and what can I do to cure these plants?
I suspect this is Physiological Leaf Roll.
Here is a link with more information.
