tx_flower_child... Hi read the posts above and in many cases it's actually hard to diagnose a orchid problem without actually seeing it first hand. A pic is not always helpful. Sometimes different treatments can help. I'm guessing that the moss and bark is old from the pic.
One hole in the bottom of the pot has deprived the roots of air and contributed to the break down of the medium packed in the roots.
However from the pic after I expanded it the moss looked as though the it was old breaking down and rotting, and had very little bark as bark breaks down.If that was the case once you removed the plant from the plastic pot the old moss and bark break down can become to acid for the orchid and cause issues. This disrupts the micro climate in the root system as the ph is too low for the orchid to thrive. I use test strips to check the ph. After removing the orchid from the pot and removed all the old moss as well as cleaning out any black, squishy or dead roots then I spray the roots with peroxide and let sit for a few days just air and light to generally see if there is any improvement. If the roots are green it is usually hydrated, if the roots are grey or dry they are dehydrated and need a water soak always using sterile distilled water.In many cases the leaves may begin to return to the turgid stage and slowly recover. If not remove damaged leaves carefully looking for any signs of rot in the crown of the leaves. Generally if there in no rot in the crown then in many cases the orchid will recover. Dead plant material sends off a gas that can encourage more damage to the plant. It takes time and patience and after a few days of rest then sometimes it can helpful to treat the plant with a spectrum of light for healthy root growth once it begins to recover. Within 3-5 weeks should be back on track once repotted with fresh orchid medium, or water culture . I have half my orchids in water culture and the other in orchid medium .
You can also purchase foggers on timers and light with led color spectrums on timers according to time of year for supporting healthy growth. The light spectrum can be changed to support floral growth once the stem begins to swell and form a bud.
There are a variety of orchid care guides on you tube. Sometimes it helps to see the orchids with techniques tried and true from experienced orchid lovers.
Hope this helps. Good Luck.
