Dove orchid dying

The photos you referenced in your first post show one mature pseudobulb (the large round wrinkled one) and one partially mature pseudobulb (which has some leaf bases sheathing the pseudobulb.) I refer to these as the older growths. If your plant is going to survive it will make new growths from the base of one or more of these. The new growth will begin as a green pointed shoot at the base of an older growth. It will elongate and eventually leaves will be visible. The growths you see on your plant began that way at some time in the past.

Orchids with growths emerging laterally, one after the other, from the base of the older growths, are said to have a sympodial growth habit. The pseudobulbs are modified upright-growing stems that function as water and food storage organs. In a lot of orchids, like this one, they are short and near-globular. They are connected one to another by a section of horizontal-growing stem called rhizome. In some orchids, like this one, the rhizome is very short between pseudobulbs, and people normally don't see it. In others, like some Bulbophyllum or Cattleya, the rhizome is a lot longer. With most sympodial orchids, new growths come from dormant buds at the base of the pseudobulb, but sometimes new growths can come from the rhizome. People often refer to pseudobulbs as "bulbs." If the pseudobulbs are elongated, as happens with a lot of Dendrobiums, people sometimes refer to them as "canes" or "stems." People also use the word stems to refer to the structures holding flowers. So I am not quite sure what you mean by the phrase "new pseudobulb or a new stem", but I may have answered your question.

By water heavily, I mean soak all the media. Pour water into the pot so all the media becomes wet. When people say "water lightly" they mean to add some water, but not enough to get all the media wet. Almost all the time, when you water an orchid, you will water it so all the medium is soaked, or "heavily."

The new roots will probably emerge just above the medium, in the air. They will eventually grow down into the medium. When they are in the air they are at risk of drying out in a hot climate. Once they grow into the medium they will be fine with normal watering of alternating between wet and almost dry. But before they grow into the medium, you should barely wet them once a day with a spray bottle or a few drops of water from your hand. It will take just one squirt with a spray bottle, directly on the new roots.

Normally, when planting a sympodial orchid, the rhizome is set on top of the medium in the pot. The bases of the pseudobulbs are also just at the surface of the medium. The roots your plant has now should be in the medium. They are probably not enough to hold the plant upright, so you will probably have to put one or more stakes into the pot and tie the plant to the stake(s) until sometime in the future, when it becomes stable. When your plant makes new growths, they will probably emerge just at the surface of the medium, or a little above. When the new growths make roots, they will probably emerge a few millimeters above the medium, and begin growing down into the medium. You should see this within a few weeks.

You did answer my questions and i realise how much i dont know about this orchid. Thanks for your patience and taking time out to explain to me in so much detail.
Right now my plant is buried in the media upto an inch above from where the roots start. I had to do this since the bulb with the leaves is around 2 ft tall and i could not keep it from falling off. Is that okay?
I will follow your advice to get a stake for it.

The bases of the pseudobulbs should be at the surface of the medium, not buried. The new growths may not develop if the area where they originate is buried too deeply.

I would repot it, not so deeply. You are correct; it can be hard to repot a tall plant with few roots. You will need one or more stakes. It might be easier if you put 3 or even 4 stakes in the container, one at each corner.

Update
The leaves are less dry and are softening and not brittle like before. But one of the earliest leaves have started to yellow. Also the small yellow spot on the pseudobulb has become bigger. But the spot is not mushy.
I have only watered it once since the first post and that too only after the medium was completely dry.
Unable to see any new roots as of now.
Is the issue getting worse? Any further suggestions please?

You have to wait. The plant will not get better until it makes new roots. It is impossible to predict. Keep watering when dry.

Things take time. Have patience, don't be quick to keep changing things or you'll kill it.

Will definitely wait but dint want to wait too long with the updates for the fear it becomes too late.
I will continue to follow your advise. Thank you estacion seca and orchid whisperer.

Orchids grow more slowly than understanding in a human.

Update
The yellow areas on the pseudobulb that i had mentioned earlier has turned brown and it is soft to touch. Is there anything i can do to control it or stop further damage?

[estación seca]

I would take a very sharp, short knife and cut away the soft brown area.

If, after cutting, you still see brown, sterilize the knife with 10% solution of bleach (sodium hypochlorite sold for household use) or 70%-90% isopropyl or ethyl alcohol solution if you can get that at a druggists'. Then repeat cuts until you no longer see brown.

It may be the old pseudobulb is completely dead at the base, but the newer pseudobulb is still alive. The newer pseudobulb shown in the photo in your link can still recover and grow if the base is not dead.
