White crust near airlock

[sime13w]

First time brewing and I just put my 5 gal batch in the primary yesterday and it has been busy on a few hours after going into the primary. I noticed a crust at the bottom of the airlock near the rubber ring on the bucket lid. Should I be concerned?

is the crust from a previous batch or is it from the current fermentation going nuts?

Current fermentation.

its fine, just clean it off, and sanitize it.
