Help me bloom my Paphs.

[Singingirl96]

Hello All.

I purchased two Paphs last year in March. Both were blooming when I brought them home, and the plants were very healthy.
14 months later, the plants are still very healthy. There are new growths in both but they refuse to bloom.

I have them indoors by a east facing window. It gets a lot of morning sun. The medium is a fine fir-bark mix specially made for paphs, the temperature is 60 - 70, and the humidity has been low in the winter, but now is about 50%. I water it about twice a week when the medium is almost dry.

The new growths in one of the plants is growing one more leaf.

Do any of you have any suggestion of what else I could do to make them bloom? I should mention that I have several catts that bloomed and all of my phals bloomed, and they are all by the same window.

Here are some pictures of the plants today, but I'm also including images from when they were in bloom for reference.
