Hi! My mint plant is having some slight issues.

The edges of some of the leaves are turning yellow/brown. I read this could have to do with too much (direct) sun. The mint sits on the floor in front of a north facing window, which should be okay right?

I already snipped off some of the leaves, but it keeps coming back. Also, can I still use the brownish/yellow leaves in my food?

Edit: Here are some photos.
