Everything it appears progressing well - a new leaf and poking roots is a great sign that Phal enjoys its new environment and is growing.
Notice that at some point, the roots may take some room in the pot. The way not to overwater it in the slow growing winter time is to just take out some bark to create more air pockets and allow roots to breath.
As an observation, when the cooler/shorter days come, it would take longer for the roots to dry (sometimes over 10 days.)
Happy Growing!
