All looks normal to me. A plant is a living being. They are not 100% perfect, 100% of the time. Your plant looks healthy and worrying about a couple of tiny dots is like picking on someone who has a mole on their cheek or a couple of freckles! Nature has many variables and your plant will show many throughout its' life. No plant is madeor grows flawlessly.
