I’m probably just being paranoid, but I assume the stuff floating around is the yeast having a party eating up the sugars?.. This is also 27 hrs after pitching the yeast.
That Hop debris tends to have the most shock value; its green, and just looks wrong. So until you’re used to what it looks like, it tends to get mistaken for something nasty. Your picture looks fine.
