Hi KrystalGem and welcome to Orchid Board.
I'm afraid I think it is possible your Phals roots are rotting
Phal roots like to breath and the easiest way to allow them to do this is to ensure they DO dry out between waterings. If the roots can't breath then they will generally rot.
Often the first signs of root rot is flowers dropping before they should and leaves dying.
It looks like your medium is sphagnum moss. You mention soil, is it the moss all the way down or is that just a layer on the top. Phals should not be grown in 'soil' as such as it is generally not airy enough.
The most common mediums for Phals (and many other orchids) are bark or sphag. Many people (including me) find sphag holds the water too long though and it is a common cause of begginers getting root rot. It can seem dry on the surface and be soggy lower down.
Another comment is, does the pot have holes in the bottom, or is there an inner pot which can be pulled out and which has holes. It seems far too many Phals are sold in pots without holes in the bottom and that also leads to rot. They should not be left with water standing in the bottom and if there are no holes in the pot then the water just stays there when you water.
So....
the first thing I would do is remove it from the pot and take a look at the roots.
Are the roots firm or are they mushy/hollow?
If they are firm then they are good roots, if they are mushy/hollow then they are rotten/dead.
Remove any rotten/dead roots with a sharp sterile knife. You can dab a little cinammon on the cut end, but don't use too much as it can by too drying on roots. Just a little dab on the cut end can help stop infection.
Do you have any/many roots left?
Does the sphag smell bad?
Were there any holes in the pot?
