Rough vertical ridges
Looks like under extrusion, here's a extreme example.

I would check your feed rate by marking out 100 mm on the filament then manually extruding 100 mm. You can use this to verify if you are under extruding due to your feeder. If you find that the printer only fed say 90 mm when you asked for 100 mm, you will need to change your feed rate in Cura to 110 %.
If you confirm that the printer is pulling 100 mm through when you manually ask for that much, then it could be a combination of speed, cooling &amp; jitter. I would slow down the print speed and see if it improves the print quality. I've experienced issues where the nozzle is moving fast around small bends and wobbling slightly, the filament is struggling to land on the previous layer and the resulting effect looked a bit like your photo.
I can't think of anything else that might be causing this issue.
