Late Blight ??

[dipchip2000]

Trouble in paradise this morning. This plant was healthy yesterday morning and looks like this today. It is a Purple Haze that was planted March 1st. So far looks to be only two plants affected and they are growing next to each other and both are Purple Haze. My thoughts are Late Blight. I just wanted to get pictures first and now am going out to pull them and destroy all evidence.I welcome your diagnosis but will not wait to pull them. they are history and will try to keep from infecting the rest of my healthy plants.
