About a year back I received a Coelogyne brachyptera in seemingly good health, light green leaves and pseudobulbs, but I don't have any experience with these (although I do have successful growing & flowering culture with Vandas, particularly small ones like Neofinetias, Phals, Miltonia Xenia (just spiking again - DON'T bug me about the crinkly leaves, I am only just learning it needs lots of water, lol).
The leaves have slowly, progressively started to yellow and brown. Starting with brown tips an dthen brown spotting down to pseudobulbs. There has never been any new bulb growth (and one node appears either dormant or dead).
I repotted in a mix of bark, sphagnum, charcoal and perlite shortly after receiving and at the time root system seemed healthy and no rot.
It has about the same place and culture as my Miltonia, room temperatures 17 - 26C, about 45% Humidity, Norht facing Window with artificial lights (combo LED plus 50/50 Daylight + Grolight flourescents at the moment) about 1500fc for 12 hours (although I had recently moved it to a less bright spot).
I generally give it 50% Rain Mix (i.e. 1 scoop for 4l) flush weekly or when starting to dry out. (I always flush feed all of my orchids.) I supplement every month with a seaweed nutrient plus microorganism/probiotic (which has pushed my growth from "ho hum" to "wow, I can actually take care of and bloom orchids!"
It's roots that I can see near surface appear healthy and green. And some slow growth to the outer edge of it's translucent pot.
I am hoping for some potential advice from a Coelyogene enthusiast to help me deliver resuscitation as this orchid is giving me all the signs of a slow death in progress. Sigh, it has never bloomed in my care.
Any ideas? (Thank you in advance!)

I should mention that the tip browning started many months ago, which I attributed to excess light and had since moved it, but browning has been slowly progressive since then.
