Can anyone identify what is wrong with my cole plants??

3 months ago

Hi friends, I have a greenhouse here in Taos, New Mexico. I am growing a lot of greens which I have had good luck for the past 8 years growing all winter long in the greenhouse. We heat on the coldest nights, but otherwise, the greenhouse stays warm enough. I always have some problems with some of the leaves - almost always the leaves nearest to the ground. I am guessing that at least some of this is downy mildew, but I am not really sure. I do spray every 2 weeks with Greencure, and have found that that does seem to help some. But a positive ID would be most helpful. Any ideas would be most welcome.
