About the damaged growth, I doubt you'll even be able to see this damage when the bulb is mature. It also looks like a mechanical injury to me, but either way it won't affect the long term growth of this bulb, much less the plant.
Here's an update! Can't believe it's been a year already.
Several have produced their first true pseudobulbs this summer. I was more careful to let them dry out in between waterings -- they were kept too wet last year and their roots suffered.
Oh these are so awesome!! thank you for all of the updates. I got some seedlings I deflsked recently and this is very helpful! I'm battling a bit of a fungus issue with them, but most seem to be doing good. Keep us posted how your mounted babies do, I am a fan of growing them like that and will probably be mounting my babies soon as well.
