Laelia milleri / Your opinion about repotting

[Shadeflower]

I'm sure someone here would say it is being underwatered, possibly it is. The new growth is progressively getting smaller than the previous growths, now most of the time warmer temps is a simple fix for that but this is a very cool grower so maybe the opposite.
You say it gets lots of sun. The sun is very warming- great for most warm growers but a cool grower would much prefer an led light in a basement over the sun.

Just a thought.

You know what you need to do with the plant regarding repotting, remove the last 3 backbulbs that are brown an repot it with that end against the pot edge but how to get it to flower will be the real challenge.
