Dendrobium nobile - New growths are struggling

[halrac]

Good afternoon!

Though I have visited this forum many times, this is the first post that I submit.

I bought this dendrobium 2 months ago. It was in the clearance area of the shop as it had already lost all of the flowers. I reppoted it when I brought it home and it looked perfectly fine. Now, the new growths in my orchid are clearly dying (rotting, It seems). I probably let some water in them while watering

The newest leaves are starting to turn brown fall and problem is that I do not know what to do from here. I read that removing them would make the canes to regrow new ones. Has anyone ever tried it? I am having a hard time in finding more information about this.

I am afraid that the plant will not have enough energy to produce new growths as the main canes are already looking "exhausted".

Thank you for reading this!
