"If it ain't broke, don't fix it."
The repotting stress is why I now follow Russ from New Vision's advice for Catts. Watch for the roots. Each plant is different. There is no set rule for "all orchids or all Phals or all Catts." As Martin Motes suggests, "you must look at each plant every day to make sure it is growing the right way." He means check for pests, check for disease, check for water, and check for fertilizing.
With Phals, there are telltale signs when there is a problem. Usually it is the bottom leaf turning yellow. It is like the warning signal. Or if the leaves droop limply and don't hold erect and firm. Phals when healthy should have firm strong leaves that have the texture of an unpeeled fresh zucchini squash. Some are glossy leafed (bellina types) and some are duller, but all are strong.
If the leaves are droopy like wet cabbage or limp lettuce, 9 times out of 10 you will find a problem with the roots.
