White spots on tomatoes turn into holes

White spots on one, see the hole form on the other.

White spots on one, see the hole form on the other.

I have grown tomatoes my entire life, and have never seen this before. I have a few different tomato gardens around my house and the plants were very healthy and started bearing multiple fruit to begin with.


As the fruit gets larger, white spots are appearing on the tomatoes, which eventually turn into holes.

The spots are not raised, but rather sunken in, and I believe the skin is breaking down and causing a hole to form. This is a new house, and the soil is mostly clay, although I did plant the tomatoes with plenty of manure mixed into the soil as well.

Can't figure out if this is an insect problem, or possibly a soil problem? The holes look like a worm hole, however the holes are a result of the white spots softening or rotting the skin.

I have a ton of tomatoes growing right now, and all except one garden is having this issue. The only garden not showing these signs is in the backyard, and a great deal of fresh topsoil was laid, and no manure as I planted the plants.

These plants were my "runts" and were far behind in growth of the rest of my crop. So they do not show signs of the spots yet, but they have not reached the size that the others did when the spots appear. That makes me think maybe it is a soil/ nutrient issue.

Help!
