Yellow leaves on unknown dendrobium
Hello!
My first post here. I'm a relatively new grower from Australia and I'd very much appreciate advice on what to do with one of my dendrobiums. For a while, it seemed very happy in my orchid house but now it's got an abundance of yellow leaves and a fading of the green leaves. Please see the images attached. It had about 8 kikis on it - all healthy at one point but these seem to have died back.
I picked this thing up from a private nursery - not sure what sort of den it is but I do know there's more than one in there (I bought it in flower - some flowers were pink and white and some were pink and yellow). Can anyone suggest what might be going wrong and what I can do to rescue these plants?
Thanks much!
