Welcome. Sorry, I am rather new myself, and only have 1 phal, so I am not the right person to answer you. But, since it is a weekend, there are not a lot of folks posting, and I didn't want you to think no one cared about your poor orchid.
It seems you are being very careful not to overwater...which is good, as too many orchids are drowned. Phals do not want to dry out totally though, and yours looks pretty dry. Of course, sometimes when an orchid looks dry, it is hard to tell if it really is, or if it was way too wet at one time, and the roots died from that.
Did it seem healthy when you got it, or was it all soggy? And, has it been staying just a bit moist between waterings?
