Is my Phal salvageable?

[pancakelover01]

Hello,

I’m new to orchids and this orchid community and I currently own one Phalaenopsis Orchid from Target. It had two flowering spikes with blooms, one of which all of the blooms have already fallen after a month. One of the leaves already came with this little black blemish on the side. The leaves have always been droopy, which concerns me because I Water it when the roots turn silver. It was doing fine at first, but then suddenly the aerial roots dried out, and there seems to be a black spot on the crown on the side, and I’m wondering if it’s the beginning of a crown or stem rot 😭 the orchid is planted in bark. Also the leaves look a little discolored at the end, like a purplish red. I’ve no answers for most of these so can somebody please give me tips on what is wrong with my orchid and what I can do to prevent her from dying, if she is? All the roots in the pot look good still. Do I cut the dried looking aerial roots? They turn a little green when I apply water, but not really and they turn back to the dried color quickly and they feel flat, and look thin and kind of pruny.
