a few new cattleya growths

[Shadeflower]

So I just got into Cattleya's very recently, have gotten a couple to flower but most of my new Cattleya's are yet to show me any flowers, this months I noticed that a lot of them are "waking" up so to speak and are pushing out new growths. Once these appear they quite reliably grow along so looking forward to them growing and to see how long it takes them. Last one is a brassavola but I see now it is too out of focus to see the new growth unless you know where it is.

I like how you cut the cup to make way for new growth!

What is in the potting mix?
