18 gal swc
Two tomato plants
Heatwave on right BHN444 on left

This yellowing-shriveling happened fast.I had to skip a day checking all plants then the day after that it was really noticable.Before this they were healthy,dark green & many green tomatoes.The plant on the left looks ok for now but am fearful for it.I check the water every day and add as needed.
Will furnish any other info if I can
Thanks

What is on the other side of the fence that container is up against?

Most of the affected foliage seems to be against the fence...right?

Thanks for the reply
The damanage is just about the whole plant.There is nothing except a ditch & street on the other side of the fence.

One thing I'm thinking...is there a possibility that some sort of herbicide has been sprayed in/around the ditch. The sudden onset/pattern of damage looks like herbicide drift.

Other items to look for...over water (can be as bad or worse than under watering), nutrient deficiency (what is the soil mix in the containers)...
