The part that got chopped off.

I am beginner as well. This year is my first year collecting orchid. That Blue is beautiful.

Sorry, I have no help here. Some fellow Orchid collectors will help you soon.

Good luck caring new collection to both us. lol.

The "Blue" tint is caused by the injection of blue dye. The plant will probably re-bloom white. The bit chopped off was probably marked or damaged and was removed to assist in the selling process.
Do nothing, especially do not repot or fiddle in any way. The plant should recover and you should be able to defer repotting for a year. They are better pot-bound.
Find some complete cultivation notes that relate to zone 9 wherever you are in the USA. Find the spot where it will be happy and observe what happens.

It looks to me that the crown was cut off, probably rotted. Maybe I'm see the photo wrong, could you possibly post more shots of the crown of the plant? Also post pics of the pot and the roots.

If the crown was cut off, the plant will not grow from that area again. If it is healthy, it should make some side shoots from the base or baby plants from the spike (keikis).

The blue color is dye. It will not flower blue again. It is a white Phalaenopsis.

thank you guys for your responses. BTW, I already stated in my original post that it had blue dye in it.
Anyway here are some more photos of the plant:)

the roots:

The whole plant

the crown from a different angle

Well, everything about your plant looks good except the crown is gone. I would continue to care for it as you have been and hope it sends out a basal keiki (small growth from the base) or forms a keiki from one of the spikes (where the flowers are.) Your plant cannot continue growing without its crown as that's where the leaves come from.
