Accidentally Used 30% H2O2 Solution Instead of 3% on Orchid Roots

[Birb]

The title says it all, talk about repotting gone wrong.
Extremely unfortunate (and puzzling) in my part, really.

But in all seriousness my phal hasn't been taking in water since I accidentally sprayed its roots with 30% hydrogen peroxide solution instead of 3%. Needless to say its been losing water with no signs of recovery ever since and I'm freaking out.
Also it has no aerial roots but its leaves are still very much green, droopy but green.



Any help is very much appreciated, thanks in advance!
