First Coralline growth?

As the title asks, I would like to know if this is the start of Coralline growth in my glass and back. When I scrape it off it’s definitely “crusty”..

Looks like green coraline in the pics. Green can grow faster then the typical purple.

The figure-8 does look like it. Lower phosphate will speed it up.
