Is this pearling or something bad?

[cet98]

Hello, I just moved this frag of Atomic Broccoli Macroalgae from one of my 10gal nanos into my larger 20gal display.
As you can see, it started to produce bubbles all over the leaves which it never did before.

FWIW, it was originally under a Prime 16HD at the substrate (15” from light) and now is under a Radion XR30wG4 in the rocks closer to the surface but still about 15” from the light.

Thank you for any and all knowledgeable replies

Simply a product of photosynthesis :)

Or just some flowing bubbles that stuck to it.
