How to help a stressed orchid?

[Cymbaline]

Long story short my new Elizabeth Anne Buckleberry looks to have black fungus on one of them. I contacted the seller and he refunded me my money.

So I am going to give it a shot to try and save them. There were three plants in the pot, and one looks very healthy. So much so that to my dismay it looks to be in spike. My dismay because I know what I did probably stressed the plant out and I don't know the consequences. I hope I don't kill my plant.

Question: Is there anything I can do to help reduce stress at this point? I probably overly did it with trying to save my plants.

The healthiest of them all had green roots and I managed to not break any with my repot. If anything I'm hoping THAT one will get through this.

The other two bulbs have brown roots and I did end up breaking some trying to get medium off it.

To try and save my plant I followed Orchid Girl's advice regarding Black Fungus.

1. I separated the three . The sick bulb was part ( growing from ) the healthiest. So I cut them apart.

2. I remove all the medium.

3. I soaked them in 3% Hydrogen Peroxide.

4. I cut off the black fungus and into healthy tissue of the sick one.

The sick one's bulb itself looks to have rot. So I cleaned it off and covered it in cinnamon.

5. I repotted them all separately into new medium and new pots. All is brand new, never used before stuff.

6. I soaked them in water with a small amount of cal-mag, silica and a tiny amount of copper fungicide.

7. I sprinkled cinnamon powder on them.

8. They are in a warm room ( 75 degrees ). Away from my other orchids. Outside we had a cold front so it's too cold. There is a grow light in the room. The room is also a drier ( less humid ) room.

9. The sick plant is in another room.
