I purchased a Lou Sneary 'Blue Bird' in early June from a very reputable orchid nursery at our orchid meeting last month, about 6 wks. ago. I have it indoors in a south window but about 6 feet from it. Our humidity level is 50-70% and have 2 oscillating fans circulating 24/7. I spray the roots and leaves daily. It's been fertilized twice with a very, very weak MSU. I've read that purple leaves can mean a magnesium deficiency.
Anyone with 'Blue Bird' or vanda experience please help. Is this normal or can I do something differently. As you can see from the picts, it's mounted on tree fern, it was bought like this. The roots seem very healthy. Thanks for any advice you can offer.
Purple leaves can also mean it's getting optimum light. Six feet from a window is keeping your plant in the dark. It will gradually start to fail. You might bring it a few inches closer to the light and feel the leaves. If they're cool, move it forward again. Keep moving it forward and feeling the leaves. When they feel warm, move it back a few inches and leave it there.

I agree its from high/optimum light. That's kinda what I shoot for actually, but if it gets severe then it could be too much light. I agree also to touch the leaves through the day and see how warm they feel.
