Phal about 4 years old - prolific flowers. Produced two keiki - started about one year ago and planted separately about 3 months ago. Both Keiki fine. Plant now has very wrinkled/weak leaves with the latest leaf being visibly OK. Watering problem or what?
Pictures would help alot. I am no expert, But it sounds like you plant wore itself out. Lots of flowers and keikis take a lot out of the parent plant. How are the roots on the mom? If the newest leaf looks ok, she may be recovering. I wouldn't let her flower again soon.
My bet is the mom needs repotting, and roots checked. Wrinkled leaves usually mean no good roots to take up water. Check her roots and see. Hope I am wrong.

Ditto, sounds like the poor gal is worn out. One thing you might try is adding a little bit of Dyntek Protekt to your watering for a little while. It helps to strengthen the plant from environmental stresses. You might also try removing it from it's current lighting into a more sheltered location for a couple of weeks while she heals.
