Thank you, Robert. All my plants produce tomatoes, fertilizer or not, although maybe they could be more productive. My soil tests show very high phosphate and Mg+ but very low nitrogen. I guess it would have been the nitrogen, which is very important for leave growth and production as you mentioned, that would have been what helped. Since it is so important for leaf development, and the leaves were what was infected with disease, it makes some general sense to me. As a nurse, I guess, it makes me think of how poor nutrition can lead to poor disease resistance. I don't believe the TTF is organic. I think they do make one that is, but it is a powder. At least they don't claim that the liquid fertilizers are organic. I don't know why they would not be, but I can't assume they are if they don't say they are. I have been using a lot of compost, but no fertilizer, either organic or not. It was actually 10-10-10 or phosphate free fertilizer that I think was recommended.
