My tomatoes generally ripening while they are about the size of a golf ball. I planted both Early Girls and Better Boys and they both are exhibiting the same characteristics. The plants are in a raised bed and perhaps there is something in that kind of setup that could result in the small tomatoes. The location is inland in southern California so we get a little heat sometimes, but this summer, up untill very recently, has been very mild. I used Peat Moss as an amendment before planting.
