Check with Matt, the pic of leaf somewhat resembles mosaic virus ? Downy is usually "dot" like.

Sorry, just went back to leaf pic and seen Matt chimed in??? Spray and keep on growing! No stopping mosaic but she will still grow. I noticed similar last year on 2212.5 but made it to scale...

Mature plants can usually weather the virus- no pun intended, and on the 2212.5 it was sporadic, 1 in 10 leaves had it. By the time the plant went down (September 20th) it was weigh off time?

Is it on the older leaves towards the stump and main or is it the vine tips?

Ah dang! Good thing is it does look to be only on a few leaves. Rest of the plant looks good! I don't see any mites but I will check again. It is actually on a newer secondary about 7 leaves back towards the front of the plant

Henry- It is hard to identify what the problem may be as it is in the early stages of development, but I can say that (at least at the moment) it does not look like early stages of downy mildew. My best guess would be Anthracnose or Angular leaf spot at the moment.

Hey guys. Thank you! Matt I appreciate that and good to know Dan! It isn't really spreading so that's a good sign so far. I will keep my fingers crossed and stay on top of the fungicides
