Cymbidium Ensifolium- sticky stuff in roots

[MRWPsyD]

I have a cymbidium ensifolium "white snake" with some sticky amber colored stuff in the roots. I had another ensifolium that had this issue a year ago, which became black rot. Does anyone know why this is happening? I avoid the crown when watering, I water at night when the base of the clear pot is moisture free, very little fertilizer, and give it morning sun. It's potted a bit too high, so I have a little sphagnum on top to keep the pbulbs from drying until I have new roots from the younger growths. (The white dust on the leaves is just diatomaceous earth, which I'll be removing soon)

My first post so I apologize if I missed anything and thank you in advance!
