White marks on cucumber.
« on: July 22, 2009, 19:10 »
This is our first attempt at cucumber growing, and we've this week harvested the first 2, being approx 8" long.  I've noticed today, that the white spot that has always been present on the plant has become bigger, and it appeared to look powdery, and low and behold when I rubbed it, it seemed like white dust.  Any ideas what this can be.  but as I say, it seems to be healthy, and producing.  Many thanks for any replies.
