Call me crazy if you want - my experience with phals is that there is no bad season to repot - spiking, blooming, growing, etc. They seem to continue on hardly even noticing. Usually the main reason to repot phals might be excessive roots growing out of the pots, a couple of years of old leaves dying off leaving a lanky looking plant near the soil level, media breaking down - for any of these reasons for sure I'd do it any time. With the media you use the roots should clean up and go right back into fresh media without even missing a "heartbeat".
