Short leaves

[Winston]

Why are the leaves on my Phals not fully extended. They are very short and not growing like they should

[NYCorchidman]

Uh....can you describe some more or post pictures perhaps??

Phals with long and large leaves may sometimes have short leaves. I don't know why, but other than looking funny, it doesn't seem to hurt the plant at all.
Often, short leaves develop when the terminal spike is about to be born.
Other times, sudden change in the growing cycle may result short leaves. I have bought a phal in the fall with flowers on already and one new small leaf emerging. That new leaf never got bigger, but then come spring, the plant grew a large normal new leaf.

So, I guess it's just something that can happen with no harm.

Certain phals have naturally round and short leaves.

This is on all five of my plants. There are approximately 8 leaves on some of the plants and they are shorter than the original leaves.

[Paphluvr]

Do the plants all have good roots? Do you fertilize? Is the amount of light adequate?

These are all things that can cause the leaves to be smaller.

[Winston]

Yes there are a lot of good roots. Just switched to t8 lights and I fertilize

[Ordphien]

Might just be adjusted to your environment.
Phals produce thin, rigid, elongated leaves in my environment.
Even ones that came in with big round floppy leaves.

Something to consider...many times more light will result in shorter/smaller leaves. And, lower light can result in longer/bigger leaves.

I'm not talking light so low they can't grow and/or light so high they burn...just the lower end or pushing the limits of the upper level of intensity.
