I don't think fertilizer will help, the infected plants do not recover:
".. tomato leaves curl and roll upward and the main leaf petiole curves downward. In time, the leaves also become leathery, veins turn a purplish color and the interveinal leaf area turns yellowish. Infected plants will not recover and eventually the plant stops growing and dies. Infected tomatoes may ripen even when immature; however, edible size fruits are likely to be bitter. Once definite symptoms are observed, it is best to pull out the plant and destroy it."
