What are these whitish spots on my parsley?

[Herbivore000]

Hi,

I'm brand new to gardening so my apologies if this is a stupid question.

This is a brand new parsley plant. Actually these are 2 different plants in one pot. I noticed these whitish spots on the leaves. Are these pests? If so, what sort and how do I get rid of them?

Please help.

Thanks!
