Hey guys! I am very new to orchids and need your advice! I have a little Phal. which was potted in moss in a clear pot and when I saw some hairy white fungi on its roots, I cut out the bad and black roots and repotted in bark. This was about a week ago, but now I notice that all the roots are black at their bases. Plus, although the leaves are fine and there is a new one growing fast, I haven't seen any new roots since I got it in November. Is there something very wrong with its root system? ( There are not many healthy roots now

) Thanks alot!
