My phal needs urgent help

[crazyblue]

One of my new phal orchids has suddenly started turning yellow and dropping its leaves. I brought it in early march and have treated it the same as my others but i noticed that the bottom leaves were starting to turn yellow last week. Now all the leaves and two of the flower spikes have turned yellow and are close to falling off. I had a close look at its roots today and they look healthy.
I water every 10-14 days or so depending on the weight of the plants and they all sit in humidity trays. Ive even put a blind in the window they are sat in to shade them from the strong light.
Have i lost it for good or can it be saved

The only thing I have seen turn an entire plant yellow as you describe is excess light/sun. (?)
If all the leaves fall off it is theoretically possible that the plant could send up a basal keiki and thereby get a new lease on life, but I wouldn't count on that - it depends upon how much health is in the root system. Even if this were to happen it will literally be several years until you could potentially turn this around to a healthy viable blooming plant.
As inexpensive as they are now days, unless you have some emotional attachment it would be a lot more satisfying to get another blooming plant and at the first sign of any issues at all start "working" with the group here before it should decline to this extent.

That was my first thought so i moved it into a much darker area. It has 3 flower spikes, two of which are yellow but the other one is still in full flower. It wasnt the most expensive one that i have but its flowers are a lovely limey green colour which i havent seen in shops before. I'll have to see what happens to it and hope for the best

The same thing happened to one of my phals. I think yellow leaves (chlorosis) mean lack of magnesium, but I'm not sure... Anyway, my phal started to rot from the inside (in the crown), that's what caused leaves dropping.

Thanks for the help
Its gone now though It happened so suddenly i didnt have much of a chance to do much about it. I did buy a replacement last week though so hopefully no more disasters!
