This is what I meant by brown cauliflowers

Most likely boron deficiency,looking at the rest of the plant,there may also be other problems. Check soil ph before planting your rotation crop,

Cheers qidqee, the reason for the initial query was that there were healthy caulies in the same row, almost 50/50 next door to each other.

Also a bit of K def. looking at the yellow at the leaf edges. There is a high demand for K during flower/fruit production.
