fertilizing paphs the "grower" way

[weederwoman]

I have read numerous times that paphs should be fertilized lightly. Few say exactly why they recommend this. Is it only fear of burning roots? Often growers give as much fertilizer as possible to optimize growth, and therefore profits. A grower near me foliar feeds, because the strength they use would burn the roots, but they want this strength to grow the plants. Seeing their plants, I would say that paphs are happy to get as much food as they can (while staying undamaged), just like the rest of us.
I have also read that foliar feeding doesn't work on orchids because of the nature of the orchid leaf.Perhaps there is a thin leaf-thick leaf difference.
From my experience growing native flowers, when you give them more food than they might get in nature, you get bigger, healthier, faster growing wildflowers. And neither I nor the flowers seem upset about this.
I use RO water. I fertilize with MSU 1/4 strength every week. I add a smidgen of fertilizer and a dollop of well water into the RO water for watering in between fertilization. I would like to try adding foliar, but want to talk about it first. I grow my paphs and phrags under two T-5 lights, on for about 11 hours average. I grow in non-organic medium cuz I like to water.
