About 2 years ago Spritzhenry wrote a great blog on the care of these its in her blogs and called 'Awkward Orchids' well worth a read. Also if you click on O at the bottom of the page and then click on Orchids lots of questions and answers there to help you

First may I welcome you to GOY Kathie.

Is the stem still green and if it is I would leave it be and still water as and when pot feels light or the roots go white.

I have just had 2 reblooms on 2 different phals and the rest of my phals are in bud I never cut the stems and have just watered as the pot goes light.
