Pot. Burana Beauty thinning pbulbs?

[Bill U.]

Hi everyone! I have a quick question about the growth habits of my blooming-size Pot. Burana Beauty 'Burana' (PS- I know that "Pot." is an old classification term, but it's easier to stick with what is on the tag lol)

In the following pictures I have a couple of different shots showing older pseudobulbs versus the newer ones that have grown in my care. With all of the newer pseudobulbs, I have found that they are skinnier (not as plump) and a bit shorter than the pbulbs that were present when I bought it from Hausermann's last May/June. (tried to show the difference against my hand for scale as much as they would allow my hand in there.... lol)

I am curious if this is just the new "normal" that I will achieve under my care, or if it is struggling somehow? The newest growths are all slightly tinged with reddish-purple because I keep it under lights at approximately 2000fc (give or take) with some natural lighting filtering through my West window as well. The lights are on for 12 hours/day. I am able to achieve the 10°+F drop between daylight hours and night hours most nights.

Feeding schedule has been approximately every other watering at 50ppm Nitrogen or so. The entire plant has gotten a dose of Maxicrop liquid seaweed about once a month and has roots growing everywhere! I have had 4 new shoots start in the last 3-4 months.

What do you think? I am not truly experienced with catts yet and would like to get a gauge on how it's doing!
