Mini Phal wont grow

[Soonix]

Hi,

I have had 1 mini phal noid and a Pink Twilight for more than a year and they will not grow anything. The twilight is not a mini but not big like the others. Both have some root growth but thats it . In the same spot i have 3 regular phals and they are growing; roots,spikes and leaves all at the same time. They dropped their flowers and the old spikes just grew a bunch of new buds.

Can any one please tell me what the problem might be. I bought them in bloom so i know they are mature.

Soon
