Grayish Coloration on Sage Leaves

Question

What is the grayish coloration on the sage leaves? It looks like a fungus; is that common? I have it growing in a topsy turvy with strawberries, cilantro, parsley and basil. Is this environment okay for sage, or should I put it separate and on its own? Is it going to still be okay to use for cooking with this on it, sort of grosses me out and not sure what it is, so I really don’t want to eat it like that.

Sage needs less water than the other plants that you have in that planter. It will grow better if it is in a container on its own where you can water it less.
