Cymbidium with yellow pseudobulbs

[david meyer]

Hi all. I have a cymbidium that has yellow pseudo-bulbs and the lower part of the leaves are also yellow. Recently I found one new shoot rotted. Another new shoot is yellowing from the bottom also. I have attached a photo. This orchid did not flower this year or last. The yellowing was present to a lesser degree last year. I think another orchid is developing the same problem.

Can anyone help?
