Thanks for all the replies, it has made me give a second thought to how I'm growing this plant, and, in particular the note about how (per the video with Dr. Motes) imports are often nutrient deficient on arrival. I had heard about how Vandas were notoriously hard to grow and bloom (at least up in northern climates) and never assumed that seemingly large / healthy plants could have come over to me starting at a disadvantage. It makes a lot of sense, especially if you think about how most vandas you see are likely to be imports, at least in my area. I even recall my plant being listed on the Motes website as an import. Well, I have it on k-lite which supplies Ca & Mg, so that is likely helping, but it probably wouldn't hurt to give it a monthly boost for a little while with a little Cal-Mag.
With regards to dosages on fertilizer, I already do 25ppm N dosing for most of my plants that get watered 3 times a week (I target 75ppm N a week in active growth) - my vandas I was giving a bit more because I heard they were heavy feeders. My catasetums get like 300ppm N a week or more at the height of their growth, but that's a whole other story.
I guess I could treat the vandas like my other plants, not so sure now...
In any event, a tangent... Look at this root! It's almost as thick as the stem it's growing from, and now it's pushing two more from the other side. At least the plant is happy enough to grow for me.
