Not to worry...
These are a pretty easy and forgiving group of orchids ( phalenopsis).
I wouldn't do a thing until all the flowers have faded.. Which might take MONTHS!
In the meantime...
Let it dry completely before you water it again . Put it in nice bright light, not necessarily direct sun... But someplace where you might sit and read a book during the day. Mine came to me in sphagnum moss.. It gets watered once a month.. Others that I have acquired and have since repotted in a bark mix, get watered once a week. Just be sure not to leave a puddle of water on the crown ( top of the plant) as it might rot. Enjoy your beautiful plant!
