Well, nothing obvious jumps out at me as something you are doing "wrong." Sounds like you have it well in hand.
As you go into winter, all the plants will stop growing so much, so I usually cut down on fertilizer by at least half. Also you will need to cut down on your watering too (do it less frequently). The plants are just using MUCH less water and fertilizer in the winter. As a general rule for your dends, they need to be nearly dry most of the time. It helps them bloom. If you want to switch to a bloom booster fertilizer for the phal, now is the time. I would go to a balanced fertilizer exclusively for all your plants--whether or not you do a bloom booster. THey aren't growing as actively, so they don't need as much nitrogen.
Watch your nighttime temps. For everything except cymbidiums and my dendrobiums like kingianum and speciocum, I don't let them get below 60. Phals can handle slightly lower, but I'm always worried that I'll expect an over night low of 58 and it will actually get down to 48 or 50.
Watch repotting now--plants aren't actively growing roots so it makes it harder for them to reestablish. (Although if you are getting root rot etc etc it is MUCH better to repot now than struggle through to spring.)
Just my two cents.
