Leaves turning yellow and dying

[mjf45322]

Hi,

I got a couple of species ( Hookerium & Allofollium ) this past summer and have noticed that some of the leaves are yellowing and falling off. When I got the plants they were potted so I transplanted them into my regular cymbidium mix . I have not been over watering or underwatering. I have them with my other hybird and species cumbidiums. I have not had any new growths on either of these plants. Any suggestions.
Thanks,
Mike

Pictures would be nice.. This help others to assess the condition of the plant.

Were they in active growth when you repotted some plants don't like to be repotted while dormant. Also have you not perhaps overpotted them ,as this could also be a possible cause .
