Anthony--those spots, are they little white spots, purple spots or brown spots? Just thinking here without seeing pictures. Don't know if you've been spraying with copper base fungicide as a proactive measure for botrytis----but you have to be very conscious and careful when using copper based fungicides in cool damp weather because it can cause phytotoxicity (copper toxicity) wherever a small drop evaporates. It starts out as a tiny purple or whit/ tan spots that turn brown in a few days. Usually not life threatening, but certainly not something we like to see happen either.
