So what I thought was STN turned out to be a much more rapid tissue loss (infection?). This video shows how quickly the tissue was browning up and dying. Is there such thing as brown jelly for SPS? https://photos.app.goo.gl/0mE6bIUaMr1h0CRo1 After it was finished with the Setosa, the infection started to spread onto the poker star I extracted the larger chunk of the poker stars and cut away the dead stuff. That seems to stopped the spread.
