No, no plant will ever have 100% perfect leaves, 100% of the time.
Leaves like this are common and perfectly normal for cannabis plants.
It is not a disease or deficiency or anything you have/have not done.
It is not something to be worried about.
Other than the odd "freckle", your plant looks beautifully healthy.
The dots are only on the oldest leaves of a VERY young plant... Since you didn't link this to a diary, we just have to assume things here but I'd say this is nothing to worry about... those first leaves often do weird things that are simply unexplainable...
Good luck with your grow!
