Looks like you may benefit from some Extra Restart Distance. This setting is located under the Extruder tab. It will tell the printer to extrude a little extra plastic each time it un-retracts, such as at the start of these outer perimeters, to fill in gaps.
If this does not help things, then we will probably need a factory file to see exactly what is going on. It may also be helpful to know what model of printer you are using and any modifications that have been made.
