Herbicide damage or CMV

[PatrickArtist]

I have what I thought may be herbicide damage on several plants, but it has been a few weeks and they are not growing out of it and it seems to be spreading to other plants. I thought perhaps the plants that are beginning to show damage just received a lighter dose and are taking longer to show signs, but I am beginning to fear the worse. Is it possible that this is just herbicide damage and I'm being pessimistic, or am I doomed? At least half my plants are showing some symptoms and if it is CMV, many more are likely going to go down.
