with Daisy on the new roots. Well done on the rehab. Phals do easily get that wrinkly leaf thing, and it can take a little while for the leaves to plump up again so don't worry about that. A lot of people give up, and throw out their plants when they start to do that, which is a shame as they usually are just pouting and will recover.
They also sometimes pout about a change of position, so if you can find a place where they can live all the time, that is best. Your east facing window is great, as Ken said but the sun at this time of year can be pretty intense so keep an eye on it. Morning sun through the cooler months is great. Mine get direct sun in the morning until about 9am and then are entirely in shade. (but I am in Florida, very strong sun)
