Hi guys!
In a previous post I showed my beautiful NoId Phal (
http://www.orchidboard.com/community...-beginner.html ).
Everything was going great, lots of roots, strong green leaves, and even recently a strong spike emerged, with four ramifications so far, and what appear to be a second spike as well.
But now it is yellowing the leaves. They start to get dark red in the tips, and it then evolves to yellow, with something like "old skin" feel, and then the leave falls off. It happened to two leaves already, and *all* the leaves are getting red on the tips, so I guess they will all fall out

But the spike seems to be OK. I don't really understand what's the matter. I mean, the plant in on S/H, it should be with the right amount of water, not too much and not lacking it either.
Can anyone help me? This phal is very special to me! Thanks!
