Disastrous morning here. I noticed last week that some of my Phalaenopsis orchids had something nasty going on in their leaves. Finally checked it out and it seems it may be a leaf rot. So I brutally hacked away at any leaf with damage, dusting cut wounds with cinnamon, as advised, because it is supposed to be a fungicide.
I have five of these, all looking a bit sorry for themselves. The only one untouched (so far) has purplish leaves, which makes me wonder whether anthocyanins may somehow protect against fungal infection.
