| as long as you have new growth an orchid is OK.
Those new growths should continue to get larger and a pseudo bulb should begin to form when they are near full growth.
I am sorry if I frightened you more than necessary.
When Oncidium alliance rot, the new growth will come off the plant with the lightest pull. Usually all the new growth will come off in a few weeks when this happens.
You should always judge an orchid's health by whether it has new growth actively growing.
If the yellowing bulb was rotten it would get very soft very quickly. If it does not feel like rotten fruit it is OK to leave it. Just keep an eye on it.
