Is my orchid healthy?

[Sanya246]

I got gifted this dendrobium orchid a few months back, since then all flowers have fallen off and new canes have grown with leaves. ( sorry I don’t know the correct terminology)


So, it initially came in a plastic small pot but everyone had advised to put it in a bigger pot. I did that but now 2 people have said the medium looks too dense and because of the wrinkles on the older canes, it appears to have a root problem?

Please help me, currently it is in the potting medium which it came with from the store and I added a few bark pieces and fertiliser.

I also have new white spikes at the bottom of the plant which I think are new roots? So does this not mean that my plant is healthy ?

I have attached pictures
