I've seen those same creases with fruits that developed up against the wires of cages and also fruits that developed up against large main stems of plants that were sprawled. And If you're really lucky with cages you can see such creased fruits from wires and stems and also from fruit crowding and that's as follows.
You can also see them when several large fruits develop closely on a truss and they kinda bump into each other.And that can happen with sprawled plants as well.
I don't think so. He said MANY tomatoes looked like the one pictured. If you look closely around the indentations you see wrinkles in the skin as if it shrunk rather then being unable to grow out. Something strange going on. Ami
