White fluffy stuff on plant

[Lama]

Newish 15 gallon tank set up; since May.  Still has lots of brown algae, but there is also this whitish fluffy stuff growing on the pogostemon stellatus octopus.  The white stuff also has grown on the glass.  Other plants include dwarf lily (second bulb as first one rotted), Monte Carlo, water sprite, golden Anubis, and tropica crypt.   Sponge filter, 7.2 pH, 0 Ammonia and Nitrites, and 20 Nitrates.  Kh 3, GH 6.  The water is cloudy today.  Led light that came with the Aqueon tank and is set for a 6 hour timer.

I’m wondering what it might be and if I need to take a proactive approach to it?

Yeah I honeslty have no idea what this is. This is the first time I have ever seen anything like this. Most likely it came with your plants and spread in the tank.
