The problem in my case was due to pouring the chems in too fast, overflowing the funnel, and having fluid enter through the top edges of the funnel, rather than through the bottom. This causes developer to streak down the film from top to bottom, which is a disaster. If this is the case, you need to pour more slowly, so that the funnel doesn't overflow. It is much harder to overflow the Patterson tank, because the funnel is much bigger and the top edges are visible.
I do the pouring manually (no lift) and I think you found the root cause here of my problem. Indeed I pour the fluids in quite quickly, cause in the past I did it too slow and than certain parts were developed more than other parts. The marks on the images look like fluids running.

Thanks for this one! I will do a new batch the weekend and then pour more carefully
