I think you are doing very well. The color on the catts is fine. Those are tiny little guys... They are a ways from being able to bloom. But you will learn a lot of lessons by growing them. I would say your culture is fine, you could probably increase the fertilizer strength a little with the catts.
P-bulb count and bloom: When a plant is growing it starts with small bulbs and progressively puts out larger and larger growths. Once a plant gets to mature size - the latest p-bulb being full sized - the plant will start preparing to bloom. This usually is happens in catts on the 2nd or 3rd mature size pbulb, as the plant needs strength and reserves to bloom. At that time the plant may have 5 p-bulbs or 15. It depends on the plant type and how it has been grown. Early growths may have died off by then, leaving only more mature growths. Or if all the growths are still alive, you could have a full pot with only one bulb capable of blooming. When people talk about how many bulbs are needed for a blooming sized plant, they are usually refering to how many bulbs must be included in a division, or how many mature bulbs there must be.
I'm very impressed with your phal recovery. I certainly couldn't have done any better (not that I'm any hot shot phal grower...)
