M. tenuifolia converted to S/H. Is it ok?

[Chlorophile]

So, I finally got the hydrocorn and rinsed it and then soaked it in Kelpmax over night. Today I unpotted the orchid and removed all of the sphagnum moss and rinsed the roots clean. I trimmed off all the dead and dying roots. There are quire a few brand new roots starting to grow from the psuedobulbs. I left the healthy looking mature roots. How's it look and did I miss anything?
