There is still time for it to bloom. Peak flowering here is September/October so counting back 110 days you get May/June. November/December there. Do not give up hope.

There are a couple of FAQ's to read about Phal. blooming and if you give more details about your growing conditions the locals will be able to assist.

BW:

The amount of light coming through a window may vary due to direction, outside objects such as trees or awnings, and weather/clouds. I have many of my phals right next to windows that face north or east, west with an awning. Though phals are lower-light orchids, they still need good bright light, just not direct sun. Phalaenopsis species grow in shady areas outside, inside a house without any light is just too dark.

Which direction does your window face?

What are the nutrient numbers on your fertilizer? Some are for growth, others for blooming, others for general use. I prefer an even-numbered fertilizer (like 20-20-20), used weakly (1/4 strength) at each watering throughout the year.

Phals do not thrive in temperatures below 55 - 60 degrees, depending on their genetic makeup. The cooldown you describe may help start spiking. It has started cooling down here in Las Vegas, and spikes are starting to appear on my early-spring blooming phals. The summer bloomers will have to wait until it warms up again.

Hope this helps!
