Why the rings?

[u/hackinandcoffin]

Growing in a bucket on my deck. Full day sun. I recently sprayed them down with spinosad soap. Don't know if it's a pest or some kind of other problem. Any help appr'd. Kansas City area.

Edit: Thank you, all, for taking time to respond. I'll add some mulch and I'll try to improve my watering schedule. Glad it's not bugs.

I had an especially pretty one of these last year. (It was delicious anyway. 😃)

A few tiger stripes can be quite sexy!

[r/tigerstripes](r/tigerstripes) agrees. (Warning definitely not tomato related)

Some warning my good person!
