    well it depends on what kind of potatoes. Could be they are older and starting to seed or they could have had frost burns on them or could even be a disease.

    Very alkaline soil can make 'scabs' on potatoes you grow. Oak leaves used for compost or mulch will do this.

    Potatoes DO NOT LIKE fertilizers...you can grow potatoes inside a tire with newspapers! The scabs are due to too much fertilizer in their growing medium; add sand, leaves, shredded newspaper or paper of any type that you have shredded up...just keep it moist & continue to bury the potato plants as they grow...leaving 'a little' green showing.
