Toadstool not extending tentacles...

[Rubber Ducky]

I've had these two toadstools for about 1 year, and cannot figure out why the tentacles are not extending...i have one in middle of tank in high-low, and large one in lower corner of tank

and this is the a frag off the big one that is extended in my friends tank

my parameters are 1.025 salinity, 400cal, 9.4alk, temp 78.2
Here's my babies:

I have two - one on each side of my tank. One is always open with decent extension, the one on the other side tentacles always stay short. They are different kinds and I have no idea why. Light, flow...who knows.
