lol giving it time is probably your best move. I had an issue where my java moss was dying then made an explosive comeback:
I dosed small amounts of Flourish Comprehensive each day and inserted 3 root tabs spaced from each other underneath the driftwood to try give it a chance.
Not sure if it was a big help but giving it time and leaving it alone in the tank is probably a good idea :/ Cross your fingers and hope nature does its magic. Good luck!
