Q: Little brown marks on the leaves
Michael, You are a man of few words. If the "marks" look like small dots it is the work of a 4-lined bug. Best And Happy Yardening, Nancy
Q: How do I get rid of them
Spray with an insecticide. I would recommend AzaMax - OMRI listed containing azidiractin or a spinosid based product.
