Lack of active root growth after a 'busy' period shouldn't be a cause for concern, especially in winter. Roots are not going to be in active growth 100% of the time. I've often seen them take a short break and then resume growth again, but I don't know if it's culture related, or something they would have done anyway.
For Phals in clear pots, I find that root color is a far better indicator of when to water than skewers are. When I see them starting to turn from green back to silver I wait another day and then water. I'm never been a huge fan of the skewer method.
I would unpot the plant and check. If the roots are fine, the limp leaves may be from too little water, and your original watering schedule was better for it. If the roots are in bad shape, you'll know that you were likely overwatering.
I doubt the quality of the medium is a problem since you repotted it last spring.
