Hey everyone,
I've started developing my film at home a while ago and recently I've had 3 consecutive rolls with horizontal white lines (black on the negative) across. The strange part is that the lines are not continuous across the whole roll but run across multiple frames. Please also note the marksat the sprocket holes.
I've been using my current setup of camera body and lens for 5 years now and never had a lightleak issue. Its a canon FTql with an FL 50 1.4. I'm shooting hp5+ at iso 800 and develop it with Ilfotec lc29, fix it with Ilford rapid fixer (I make a new batch every 5 rolls). I use a paterson style tank and load my film in a bag. The lines are clearly visible on the negatives so it is not a scanning problem for sure. Please see the attached images.

I'm hoping someone with greater experience than me can tell me what am i doing wrong or what part of my process might be at fault.
All the best,
Marcell
