Yellowing Dendrobium (NOID) New Growth?

[Panino]

I got this Dendrobium NoId about 3 months ago. About one week after I bought it all of the flower fell off. After that the leaves started turning yellow and falling off as well (I included a pic of when I first bought it and what it looks like now). However, while the leaves have been falling there are 4 new canes growing. On the one hand I thought I wasn't giving it what it needs because the leaves were falling... but now I might be doing something rights because there is a lot of new growth. Could you guys tell me what you think about this? I'm a bit confused... My orchid is giving me mixed signals!
