Stressed Orchid

Andrea, you can try to raise air humidity (hopefully around 80%RH or so). I'm not sure where you are located, but it is likely that you don't have enough humidity. For Phalaenopsis, the night RH is important (when they are dehydrated). You can use some kinds of enclosure so you can maintain high humidity. When the plant opens stomata, it doesn't lose lots of water if air RH is high. Then I would place it in a place with sufficient, but a bit dimmer than ideal light. The plants have to open stomata more if they do more photosynthesis, so the plants lose water. But they need enough light to grow. I would also water with the purest water with no fertilizer. Roots have easier time absorbing water with purer water. Basically, you are trying to increase their water usage efficiency by all means.

 

Andreea, in that situation, I would pot up the plant normally, watering it in with KelpMax solution, then implement Naomi's suggestions by simply inverting a clear plastic bag over the plant and pot, creating a "mini-greenhouse" to trap the humidity around it.

Definitely move it to a very warm, shady location and allow no direct sunlight to hit it, or that "greenhouse" will quickly become a "broiler bag".
