How did the move go?
Phals usually become very active when warm weather returns, which is now.
All my phals are pushing new leaves or roots, or both.
Dendrobium, as the new canes becomes a few inches tall, they usually start making their own roots. Often, quite many.
Is your dendrobium in need of repotting? old potting mix or not enough space for the new cane to grow? if not, I wouldn't repot.
also, if you would repot, I would do it now instead of waiting for the new roots to get any longer at all. The longer they are, the more likely you will damage or even cut them off while handling or potting into a new pot.
The paph you have basically has the same color, green, pink, white and some or many dots. Just varing amount of each color, but they will most likely be coloratum.
At times, there are some dark ones. I have two that are quite dark.
The shape of the flowers are quite variable though. Most I've seen are downright ugly or odd. some are nice. Many of them have pretty leaves.
The black spotting on your phal, are they really black black? because many phals develop wine colored spots on new leaves when exposed to strong light or sometimes even not so strong light.
They eventually go away.
Crown rot does not start with spots. The crown looks wet and mushy. Usually when you find out you have one, it is well underway and too late to do anything about it but toss the plant.
I'm glad your plants are all doing well for you.
