Crispy leaves?
One of my tomatoes, a Pink Brandywine, has two large leaves that are slightly curled under and are edged with black near the tip. The black part is dry and crispy-almost as though it was burned. This plant is in a large pot and I have added Azomite, Epson salt, liquid kelp, fish emulsion and alfalfa water. As with all my tomatoes, it's in a large pot. The other 17 plants are not showing any if these signs. Is this disease? Some sort of deficiency?
