Help!!! Foliage problems are scaring me...

[Anthony_Toronto]

I had a bit of this in the middle and end of last season, but this season it has started early and is more prevalent. Starting at lower branches, leaves are getting brownish spots and the green leaves are then drying up until nice and crisp. A few stems have small spots on them. As for the leaves, there are no water soaked areas, no fuzzy growth, no wilting, no yellowing (until the leaves start dying, after which the stems that have not crisped up turn yellow, maybe because the lack of photosynthesis causes the plant to cut off the branch in question), no apparent mold, fungus, or mildew, no browning, no apparent impact on fruit, but if things keep progressing like this the fruit won't have enough leaves to shade the fruit and produce enough sugar to make them grow and taste good. Appearance and symptoms don't seem to conform to the diseases I see on either of the below links. The closest would probably be some of the pics of Bacterial Canker, but its not quite a match/missing too many of the listed symptoms (leaves remain green (DESPITE the brown appearance in some of the pics), do not wilt, no yellow slime in stems). Any thoughts/suggestions?
