I've been out of town and away from my garden for nine days. I saw the first glimmer of this before I left. Now around seven of my 30 plants have it. It starts at the tops of growing tips. Curling purple leaves, some spots, then browning, then kills the growing tip. Most of my plants look okay, but they are right next to ones looking sick. I'd like to get an idea of what I'm dealing with so I can yank the sick ones if need be. Most of the sick ones are in raised beds, but spread fairly randomly around the garden. I thought my plants in containers were safe until I spotted some in one plant there too.

Thanks very much to those who respond!
