Nitrogen-stressed yeast or mold?
I am not asking "what should I do?" so I think there is no need for feeding schedule, temperatures and stuff.
Loose starter, stirred every 2-3 days, been going well for 3 months in winter, but now it's getting warmer.
Is this yeast under nitrogen stress or... mold?! It isn't fuzzy enough to be mold.
Don't think it's mold. Looks like kahm yeast. It's not harmful and happens when the yeast is stressed.
You say stirred every 2-3 days. Is it in the fridge? Are you feeding it? Ideally if it's not refrigerated it should be fed everyday.

One of these photos on kombucha looks like an exact match:
