Green on the outside. Brown in the inside.
Please feel free to link me if this question has been addressed before. For the past two years our tomato plants have shown a similar pathology. The plants start off great, but as they mature, the leaves die in the core of the plant. Interestingly, the plant continues to put out tomatoes. Below is a link to a picture.
Could someone tell me what might help this year?
