Yet another example of "Less is More" with Fertilizer

I have been very pleased with the growth and blooming of my plants since using K-Lite at only 25-35 ppm N, and it makes me wonder just what the lower limit is. Here's another example:

This is Phrag. Will Chantry, moved from flask directly into 3.5" Semi-Hydro pots about 18 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".

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.
