Thanks for the comments.
@darkosaric: There was no big change in temperature. I keep all chems in a water bath at the same temp.
@PE: I did not pre-wet the film, never have, with Plus-X or Tri-X. Could not be the drying area as these problems showed after processing before drying. I use well water so I guess it's possible there was particulate matter in the water or maybe I did not rinse the tank at first? But the other films processed at the same time were fine.
Any other suggestions? Culprits so far: dust, pinholes from temp change, pinholes from acid stop.
