Ill post some more images so you can assess the situation :)

roots and pot

the base of the crown also seems to be turning yellow... :(

And, finally, the second sad leaf. Im really concerned. I dont want her to die!!

Your problem is probably the cache pot. It is there for decoration and probably has nil drainage holes.

The plant is grown in that clear pot to get light on to the roots.

Your orchid needs bright light. Not searing sunlight, but bright light next to a window.

Thank you for having UK in your my page details at least that is a bit of a guide.

Take it out of the cache pot, put a drip saucer under the plant, read up on Phalaenopsis on the net and past posts here and see how you go.

Just a bit more.... I should have asked you about temps in your home?

Normal home temps are typically fine for phals. Based on the pictures I'd say you need to get some air to those roots and get your watering scheme down pat so that the plant isn't sitting in dankness.

"The plant is grown in that clear pot to get light on to the roots."

Do the roots need light? I thought the purpose of clear pots was so that the grower can monitor the condition of the roots and the growing medium: amount of moisture, any root rot, etc. I have never read that the roots need light.

Thanks!

The jury is out....but there is school of thought that Phalaenopsis might do better in clear pots.
Some discussion in the article in the link.

Here is a link that might be useful: Phalaenopsis culture notes

Thank you very much for the very interesting link!

From the article: "Root photosynthesis likely contributes little to total plant photosynthesis. However, because phalaenopsis roots avoid darkness, roots of plants grown in clear pots generally stay inside the pot better than the roots of plants grown in opaque pots. Roots of plants grown in bark-based media tend to grow out of their pots quickly, whereas those planted in sphagnum moss tend to have their roots stay in the pot much longer."

So I guess growing in a clear plastic pot/sleeve that is dropped inside a ceramic pot defeats the purpose! Unless you don't mind some roots testing the wind. Always learning something new here. :)

I'm more concerned about the pitting on the leaves. Could be fungal, insect or virus. False spider-mite is a possibility.
