Mystery Processing Screw Up

[Two23]

I shot a roll of HP5 in my 1954 Rolleiflex MX and processed it in a Patterson tank (x1 120 reel.) Shot at ISO 400, 5 minutes in HC110 @ 68 F, 375 ml fluid. Instead of putting the big black cap on the tank and inverting it, I inserted the little plastic rod and would spin the reel around backwards & forwards once a minute for a few times. My film strip had a light colored line running down the side (which scans & prints dark.) I can also see what looks like bubble marks in this strip. Did I screw up by not putting the black cap on the tank and inverting it? That could conceivably cause the bubbles. Could it also cause the 3-5mm line running down the side? Or, did I mess up processing AND have a light leak in the camera?

In retrospect inversion may have been a better choice.

My Patterson tank says to use 500ml for 120, maybe the film wasn't covered

Dang, you're right! engraved on the bottom of the tank it says for 120 use 500ml. Mystery solved! The top edge of the film was not covered and only got some foam on it. That explains everything. It would have taken me a long time to figure this out. Thanks!

You're welcome. Good thing you mentioned how much developer you used. The devil's in the details.
