I agree, it looks like either mealybugs or scale (some larval and fuzzy) at the base of the brown leaf. Doesn't really look like enough to do this to much damage on the leaves, though, unless they are feasting heavily on the roots unseen. I'd follow Ray's suggestion.
Sorry for my late responses. I was not notified about futher responses.

I do not have mealy bugs!! I can assure everyone of that. I am sure that the plant is still healthy. I have no idea what is happening but I just intend to observe for now.

Thanks for the advice.

I agree with the others. The plant is definitely stressed and showing this by losing leaves. Quite what is the cause is unclear! It Is quite likely to die if it carries on as it is at present.
I would cut off the flower spikes and repot and give the plant time to recuperate.

are you watering enough?
I have a psy. In the collection and had a similar issue. I found that every time I would water the plant would lose a new growth leaf. I finally worked up the courage to repot, what I’ve heard is they do not enjoy root disturbance And like to be pot bound. I potted mine in a shallow clay bulb pot. With a heavy helping of styrofoam peanuts on the bottom and a mix of small and medium orchiata or pinus radiata (kiwi bark), cut with perlite and charcoal.

Imo they need to breath a little and sulk when the media turns and they get too much water. Attached are pictures of mine. It’s in spike now, second flower about to open since repotting in February 2020. A few leaves got hit with a little mite damage In July before I could catch it.
I would recommend watering gingerly after repotting until the new roots establish.. And by that I mean only misting the sides and under the plant base Where the roots grow out..with a fine mist hand pump and hold back a true watering. That seemed to work for me. I still only water once a week at the most but can mist daily as needed.

Only when she gets dry. She is doing great with her roots. She is still healthy all over. Really firm pbulbs, healthy green spikes. One leaf has been dry and brown for four months now but her spike is still green and her pbulb is also green and firm. Just the dead leaf stubbornly holding on for dear life. If I pull it, it refuses to budge! She doesn't want to drop it. Very strange. So for me, since no one can definitively give me a fact about what is occuring, I am just going to wait and see. I actually feel better now ☺

Thanks for the advice. I am going to leave her be however and just observe her for now. If I see her start to deteriorate at a more alarming rate i.e., her pbulbs start to rot, then I shall remove and repot asap!

keep us updated, please
Will do. I have just had a look at her and surprisingly, she appears to be in full bud again. One bud is through the sheaf and the other two are just swelling up inside of theirs. The last time, the buds turned yellow and died. They had green leaves then, now there is two brown ones. Very strange.

I will let you know whether they bloom or not -

I have Psychopsis Mendenhall 'Hildos' which is growing well and has never had problems but I was told when I got it that it needs to be repotted annually because it does not tolerate either stale compost or mineral salt build-up. I use medium bark and the plant always dries out between waterings. When repotting I mostly drop the plant on to avoid too much root disturbance. So far, so good.
