Nice pictures. They do help diagnosis just what a person means by "chlorosis."

As I responded in your first post, it's weed killer damage.
Contact can be direct, as in mis-applied spray, or indirect, as in floated on a breeze.

So, have you, or a neighbor, used it anywhere in the vicinity?

You nailed it on the head Jean001! Glysophate poisoning from Roundup 'drift' from a neighbouring soybean field. The problem is I can't get mad at the culprit because that person would be...me.

I'm actually surprised because I stood there while the sprayer went by and you can see the line in the soybean field where he left a buffer for my garden, as the beans are swallowed by the weeds, and the breeze was going in the 'right' direction, but I guess not a big enough buffer.

I have since learned that it takes only 5% of the normal amount of glysophate applied to a tomato plant to kill it, so this goes out as a warning to all of those using Roundup--steering clear is not enough.

Some may pull through this but ther are a few that have bit the dust.

Thanks again Jean001.

Yes, tomatoes are very sensitive to Roundup and other products containing glyphosate.

Don't know the size of your planting. But if it's reasonable, you could cover the plants while the soybeans are being sprayed.
