What am I doing wrong?

[Subrosa]

I figured to combine a few questions into a single thread. I've been growing orchids for a few years now, with increasing success. I rarely make the same mistake twice! I am not entirely unskilled in keeping orchids. Were I the superstitious type I wouldn't mention the surprising amount of growth on some of the Polyradicion lindenii seedlings I recently deflasked. But there are glaring gaps in this hobby for me that I'd like more knowledgeable people to spitball some ideas about how to fill. First off let me preface by saying that a lack of light is probably not the answer to any of these issues. I keep all my plants outside as long as temps permit and in as much light as they can handle after acclimation. While indoors I have a large SE exposure window and lots of high power leds. But if that's what your insides tell you, say it! So, why can't I bloom a huge Maxillaria tenuifolia that I grew from a handfull of pseudobulbs? Why do I have such difficulty bringing hybrid Phalaenopsis into bloom? And why can't I bloom a Bulbophyllum of any type? Fire away!
