Are Psychopsis spikes known to grow slowly?

[YetAnotherOrchidNut]

I see some growths on my Psychopsis which I think are spikes, they look similar to new pesudopods but are much skinnier, have different tip shape and grow out at a different angle from the existing pods, almost at a 45 angle away from the plant. I can also see what is clearly a new pseudopod, and the shape is quite different.

Assuming the growth I see are spikes I notice they seem to be growing super slow. Is that to be expected? Could it be temperature related maybe?
