I recently added a DIY Co2 system to my 60g aquarium. I am seeing
streams of very tiny bubbles coming off of the Vals. I have also seen
larger bubbles appearing on the under side of the leafs of my anubias
nana and barteri. Is this typical of "Pearling"? Can pearling occur
on the underside of a leaf.

Yep, pearling it is.
