Yellow inside tomato fruit
I'm hoping someone will know the cause of my tomato problem. I've tried researching and came up with nothing. My tomatoes look fine on the outside, nice and red. But beneath the skin the fruit has yellow veining. The outside wall, just beneath the skin is often very yellow in large areas. The same symptom is happening on all 3 of the full-size indeterminate varieties I'm growing this year (not grape or cherry). I'm thinking it's some sort of nutrient deficiency or possibly the heat? I had this problem last year, but to a lesser degree. I would very much appreciate an explanation if anyone has one.
