Because your phal is potted in sphag, it is going to take longer for it to dry, and the skewer method works okay for this type of medium. Others might recomend that you change mediums, but I have a couple of Phals in sphag, and you just have to be more careful of watering, or the roots will rot. I have one monster plant in sphag that only needs to be watered about once every 10-12 days. I personally do not recomend repotting this plant until it starts to feel better, as it is already stressed, and repotting will stress it further and may tip the balance completely. Phals generally do well with repotting at any time, I have found however that a switch to a medium that dries faster (such as bark mix) that the plants do go through a period of stress and adjustment. I do not mist my Phals, but I am looking into humidifiers. In my opinion misting a Phal is just inviting problems.
