Flowers falling off after repotting

[tasha]

Hi everyone,

I am a new orchid owner/parent and I recently repotted my orchid as one of the flowers were falling off and one of the leaves was turning yellow. Upon inspection of the roots, some of them were rotting so I trimmed the dead, rotting ones off, and accidentally trimmed a few of the yellow ones in the middle, because i thought it was rotten but it was actually firm and a live root. i sprayed the roots with diluted 3% h202. And cut the roots with sterilized scissors.

My question is, i just repotted it 2 days ago and now the flowers are all wilting and dying. the leaves look good, and only 1 leaf was totally yellow and wilted so i cut that one too.

Is it the trauma of the repotting that is causing all the flower s to wilt? They were healthy looking and robust before repotting (except for the one that was wilting and fell off) Or the natural process of them dying. I just bought this phalenopsis around 1 month ago.
