This is my second year gardening. My plants did very well last year. I did the same things this year as I did last. My plants were very happy and looked to be thriving and over night all of my tomatoes and cucumbers (very far apart in my yard) look horrible. Can anyone tell me exactly what is happening? The only thing I can think of that happened right before this was I sprayed with neem oil. I accidentally used our tap water from the house which is softened with salt (which is considered high in salt by a water test) instead of filtered water like I normally do.
