Don't know exactly the care you've given them but for me, most of my phals are pretty much spent and new roots and leaves are on the move. I'm no phal maven, but unless you have a summer bloomer or are forcing blooms for retail sales, most phals are in their growing stage for next year's flower show. Some even believe you should be using a higher Nitrogen based fertilzer for leaf growth now and in late July/early August switch over. In the fall I understand an increased day/night temperature difference (15 to 20 deg) will help spike phals and other orchids like cymbidiums. Worked for me this year....
