Looks like it could be algae from watering the plants with fertilizer maybe?
A good cleaner with oxy or bleach should suffice to remove. Hopefully your sealer/impregnator kept it from penetrating too deeply.

Hi partners,

We cleaned and sealed this pool deck almost a month ago. Customer just sent this picture of green staining around plant pots.  Any ideas what could have caused this?
