What is floating in my mead?

So I added about 8 fl oz of hibiscus water (i.e. soaked 0.75oz of dried hibiscus flowers in hot water for 20min, then cooled it to probably 80F) to about 100 fl oz of lingonberry mead, and immediately it looks like something started congealing or something. The mead was already cloudy, SG of 1.020 so close to finishing primary but still fermenting, but this seems odd to have these globs of stuff floating around.

Any ideas what this is? I used bottled water for the hibiscus and strained the flowers out through cheesecloth.

Looks a lot like a tannin and protein coagulation, but I'm not familiar with the ingredients in your mead.

It's a simple mead with mesquite honey and IKEA lingonberry syrup with 71B. It looks like those floating globs have either settled or floated and in the middle it's perfectly clear. So adding the hibiscus clarified it apparently.
