Ender V3 KE Z-axis printing issue

I am having trouble understanding what is going on here. Every time I try to print something that is tall, it always has a distinct line going through it from top to bottom. I am using PETG @ 250 nozzle, 70 bed. Hopefully you can see what I am referring in to in the attached picture. I thought it was wobble, but everything seems to be adjusted correctly. Any help would be appreciated.

Possibly Z seam alignment, try it on random and hide seam.
