Negative Streaks

I wonder whether I might solicit opinion from the pool of expertise. Behold a crop of a rather unremarkable photograph of two remarkably cheerful folk strolling Greenwich Village on a halcyon Saturday in early March. Behold the dark vertical streaks in the space above and between their heads. What could account for such streaks? My first thought is that I need to change the fixer.

Any thoughts would be received with much gratitude.

Here are the specifics of the exposure and development.

Leica iiiF
50 Summicron
f/5.6 1/500s
TMAX 400
Yellow Filter

HC-110 Dilution B (1:31)
5.5 minutes at 20 degrees celsius

My first guess is that development was done in a daylight tank, and agitation was done by simply inverting the tank, without giving it a twist as the tank was inverted (by twist, I mean doing a spiral motion along with flipping the tank upside down and back). My second guess is that it is not the fixer.

Edit to add: If you suspect the fixer, then you can run it again through fresh fixer and see if that removes the streaks.

My favorite question is "What does this button do?"

Insufficient agitation.

Here's a video I made showing how I agitate.

Ah yes, thank you both for your responses. I agree that it may be an agitation issue.
