Very nice job growing these en3rmax.
Have you given your 'leaner' a cool off period?
If you can give it about a month of night time temps. around 58f and day time temps around 70+F or so you should get a spike quite soon after.
I like to put the leaners up on a shelf so the blossom spike hangs down and you look up into the flower(s).

The room that my phal's are in is kept warm through the day and the heating is turned off during the night so this should be ideal.
