Many spikes on phal, please help

[KerryK]

Hi,

I am new to orchids. I have owned this phal for two years. I wish that it came with a handbook. I have made many errors. I repotted it last year and started watering it weekly weakly with 19-31-19 orchid fertilizer. I read that this fertilizer many encourage new growth, but not necessarily blooms. So this last week I changed to 20-20-20.

The plant currently sits in a western bay window where it get indirect light all day. I live in Michigan in the woods and my house is quite shaded. My southern windows are dark since I have a front porch. I have one eastern window, but it receives partial shade as well. I have few windows to work with.

My questions are:

-what is going on with all these spikes?
-what do I need to be doing to help the plant?
-is it getting enough light?
-can I move it to the outdoor deck with partial shading?

Thank you!

Kerry
