S/H ultimately not for me

[MT-Phal]

After a year of having my phal struggle through S/H, I hate to say that I'm putting it back into coconut chips. I'm not sure why, but the roots which grew into the medium never really enjoyed the environment. They would begin to turn brown and eventually black after a few months and I couldn't figure out the reason for this. I utilized H2O2 and Physan, which may have kept them green for a longer period of time, but ultimately could not save the root. I think this is the best decision though I regret having spent the time and money on a failed experiment.


Well, moving on! I still have plenty of physan and MSU fertilizer left... will this fertilizer be okay to use in this medium? Any idea of what the proper solution mix should be?
