Dendrobium kingianum bumps?

[ceb_010]

Hello! New here and fairly new to orchids other than phalaenopsis.

I have a kingianum who put on new growth and on that cane it has these bumps. My first reaction was scale since I’ve been battling that on other plants 😫
But these do not come off and appear to be a part of the plant. You can see it looks like there is a dried bump on the old cane.

Thoughts??
