Those streaks are from over-agitation when developing, instead of camera light leaks.

I think it's called bromide drag. It's a processing problem, not a camera problem.

hmm really that's weird because i would have thought if anything i'd be guilty of under-agitation if anything.. HC110 dilution b 7.5 minutes i agitate for about 20 seconds to start off.. then twice more throughout the rest of the development time..

I'd say you didn't fix long enough.

ok well i guess i'll have to investigate my processing technique then.. i guess that could/does make some sense as i started developing using HC110 when i got the camera.. was using Rodinal previously without this ever occuring. also i am getting a strange yellow staining on my negs too.. obviously that can't be a camera problem. 
hell ok thanks guys back to the drawing board i guess.

You have nothing to lose, you could put it back on the reel and fix for a few more minutes.

ok upon investigating bromide drag.. it appears that i may well be not agitating enough.. also i think i could probably use a refreshing of my fixer as well.
for posterity here is something on bromide drag:

also anybody know what could be causing the yellow staining?
and thanks for your responses they are appreciated.

Well, your film looks underdeveloped to me and that could cause it.

I'd suggest going back to square one here. Mix fresh developer, fresh fixer, expose a roll of fim and load the tank. Follow the manufacturer's directions. Pick the time for the developer temperature. Is your thermometer accurate? Agitate for the first 30 seconds. Agitate 5 seconds every thirty seconds after that. Rinse in water. Fix TWICE as long as it takes to clear. You can safely open the tank after a minute in the fix. Agitate it in the fix too. Wash. Now, how do THESE negatives look?
For now, rather than trying to figure out what mistakes you made, or learning how to control the damage, concentrate on learning how to do it correctly from the beginning.
On these forums you'll find all sorts of exotic techniques, like developing with no agitation, using exremely dilute developers, developing in coffee, all fun fun fun, but you need to master the basics first, then it's play time.

Agreed. I just saw some wonderful examples of this in a Time Life books series on photography printed in the early 70's.
