Quick update, repotted the Phrag, much to my chagrin, but found nothing in the old mix.
Decided I was going to experiment a little with trying to emulate it's natural environment. It's found growing along the edges of rivers, so for the most part the roots are completely under water. So I used a very fine bark mix since that would allow the least amount of air flow and the most amount of water to sit around the roots. But I filled the bottom of the pot with packing peanuts to allow the water that I have it sit in to get to the fine bark.
Hopefully this plant will appreciate it's new mix, and continue to bloom better and better!
