How to help my phals bloom?!

[Priya_H]

I have 3 phals and they haven't been blooming. It's Spring and there's new roots and leaves, just like it was last year but no spikes. And I don't think there will be any. They're healthy plants, growing in Pro-Mix Orchid mix (coconut, coal and I forget what else is in there). I got Plant Prod Orchid fertilizer and it's the ONLY ONE I can find anywhere I look. I bought it...then found out it's a high nitrogen one...so it won't help with blooming. So now I can't even feed them to help bloom! Is there anything else I can do? Any homemade fertilizer (I can't compost...live in an apartment with no outdoor space ) Plants get plenty of sunlight and moisture (daily sprays). I do move them (because I don't want them to get too much and too little light). What can I do to get them blooming again?!
