Well that does seem to be pretty happy.Leaf colour is a bit yellowy but may be it,s the partiular hybrid ?
I have Phals with leaf colour ranging from the same as that 1 to almost red ,
some of this is down to the HPS lights & some down to particular hybrids.The mini phal i saved has almost red leaves but seeing as the flowers are purple i,d expect them to have a fair amount of red .
Give it a dose of Epsom Salts & see if that corrects it
