This is layer 2 or 3. It will be covered by the next few layers but I feel like it shouldn't be this fugly. I'm using Cura's Standard Quality except for temp which is set to 205. The filament is Inland PLA.
I second z offset. Weird that this happens only at a certain regular "column". Could be hiding an underextruded strand on the level below. In that case your temp might not be stable.
