Stunted Leaf Growth on Phals

[orchidgirl82]

Hi everyone,

I have two Phals that aren't doing so hot. They both have semi-weak root systems and I've been doing my best to keep them going. I was excited a few months ago to see that both of them started growing one new leaf but after several weeks I noticed that they both stopped growing and now it is months later and there is just a tiny tip of the leaf in the center but it hasn't come up and doesn't seem like it's going to. I'm not sure what to do to get these plants back on the right track. They aren't growing any roots or leaves.

Does anyone know how to help with this?? Thanks!
