I'm having trouble figuring out why my Marquette vines seem to be closing up shop for the season already. The clusters look nice, but are only at 14-15 brix, so they have at least a couple weeks (maybe more) before they're ready to harvest. Meanwhile, the vines themselves are dropping leaves. I don't see any evidence of disease and I've been keeping up with the spray schedule. Like a dummy, I didn't do a petiole test this year (and I'm regretting it), but we did one last year and it showed nothing major - just that the vineyard needed nitrogen and boron, but of which I have since amended. All other varieties in the vineyard are doing great - still have dark green leaves and look healthy. The Marquette seems to think it's the end of September when it's really only the end of August.
