I noticed this cluster of blushed fruits had developed a weird blemish yesterday -- I wondered if it was Sun Scald or Anthracnose.... I was also considering Water Rot
But today, I noticed the black/brown on the stem. This had been less serious looking before and I thought it was just the string rubbing in the stem.
Now I'm wondering if it's the dreaded Late Blight....
-- I'm thinking the damage to the fruits are not exactly like LB.... But I've only experienced Late Blight in my garden once before.... It would be an extremely rare occurrence here.
