Hi Paula!
If I may add to this -
Looking at your resting plant, I would think the plant would benefit from some good soaks. The leaves in your blooming picture shows them plump and standing, while they look a bit limp in the second picture. Take the plant to the sink and run room temperature water through the medium, avoiding getting water into the crown. At one point you might want to fertilize your plant.
I would pick up the plant after it has been watered and mentally note the weight. When you think the pot needs watering, lift it up and also note the weight of the pot. After a while you will be able to gauge when you need to water again by simply "hefting the pot"!
Hopefully when the temperature drops naturally in your house in the Fall, your plant might get the signal and starts spiking again.
Yes, perhaps you will take the time and read on in our Phalaenopsis thread.
Have fun.
addding after looking more closely at your pictures - the blooming picture shows a plant with lots of healthy roots which you buried when you repotted it. At least I think you repotted it? The plant was originally in bark as far as I can see and if that would have been my plant, I would have left it alone at that point. I find that these plant love to sulk when you disturb them like that, at least in my hands.
