Most of our 'regular' tomatoes ('Bucks County' & 'Brandy Boy') are much
larger than other years - like, 6" across. Some have big bulging
'shoulders', as well. They're kind of unappetizing, to look at. The
cherry tomatoes are normal, as are the beets and basil. We fertilized
with 5-10-5, 1#/100 sq ft, tilled in; other years, we've used just
turkey manure.

Any thoughts on why this would happen?

TIA,
George
