Candycane melting?

[nex.jenn]

Hi there,

I've had this cluster of candycanes for the better part of a year, and they've always been fine. Suddenly, during the last few days or so, the bottom group has started shriveling up, and you can even see the white skeleton on the left one. The top group that is attached to them is doing just fine, so I'm not sure what's going on. I've tried searching for answers, but I can't seem to find anything that is my exact scenario. If anyone has any idea, I would really appreciate it.

Parameters:
Sal- 1.025
pH- 8.15
No3- 0
P04- 0
Alk- 8.2
Mg- 1425
C- 500

Your nutrients zero?
That would starve everyone.
You need those two stable, available and in the range.
