White dots on plants

The Big Figfetti said:

I’ve noticed two new plants I recently added have formed some sort of white dots. It’s also on another plant in the tank that I don’t think is doing so well.
Hope these pictures help. Any ideas?

if they are new, they might need time to adjust.
they look emersed grown, and will need to replace their emersed leaves with submersed leaves.
what are the species of the two new plants you added?
i've never seen anything like them

From the photos when you zoom in, it kinda just looks like air bubbles...

Thank you! I know the two on the right are lobelia cardinalis. I can’t remember the name of the other one, I think it’s a cardinal plant though, but when I got it, it had pretty green on top and purple underneath the leaves. It’s become quite soft and doesn’t look like it’s going well. So I’m hoping the new stronger lights might help.

What does it mean that they have to replace their leaves with submersed leaves? Will the whole plant look like it’s dying or falling apart, but grow back?

This is my first time with a planted tank. Learning as I go.
