I am not sure if the end of flowering is a natural end of season thing, or if it was stimulated by the plumbers leaving all the doors open for several days, because it did get a bit chilly then, OR if I didn't water quite often enough in late August when they were in full sun.
The Miltonopsis, despite its supposed need for very high humidity, is still doing very well under more or less the same regime as the phals, and has produced a few extra leaves and roots. The leaves are still green to the tips, although a few of the smallest and oldest have withered. The question is - is it just surviving, or will it be healthy enough to flower? The test will come in spring - it flowered in March, I think, so I am hoping it will do the same again.
