Stop soaking the orchid. That might be your problem.
Orchids should be taken to a sink, watered thoroughly with Luke warm water. Allow them to drain and place it back in the location where you are trying to grow it.
Very few orchids need regular fertilizer applications. Ditch the myst.
If you must fertilize, do it once every three months at 1/2 strength.
Depending upon a lot of variables your plant should be watered roughly once every 5 days or so. The warmer the home, the lower the humidity, it dries out a little quicker. The cooler the home, the lower the light that it grows in the slower it dries out.
You will find out that orchids are not like other plants and they can't be treated by one.
