Considering how much water, and how little food an orchid gets in nature, I switched to K-Lite fertilizer (12-1-1-10Ca-3Mg) at only 25-35 ppm N at every watering in November of 2011. Since then, I have been very pleased with their growth and flowering, but it makes me wonder if even that might be excessive. Examples like this also push my thinking in that direction:
This is Phrag. Will Chantry, moved from flask directly into 3.5" Semi-Hydro pots about 18-20 months ago. They were watered in with roughly 30 ppm N K-Lite, which was supplemented with 1:250 KelpMax and 1:100 Inocucor Garden Solution. Since that time, they have only received RO water, applied via overhead
misting 2x/day, in my basement "incubator". This was not done by choice, but by too many distractions that led me to ignoring it. Apparently that's not so bad!
The leaves are a bit mottled, suggesting a bit of nutrient deficiency, but this still managed to grow and bloom. The second image shows the extensive root system, both in the pot and overgrowing it.
