You recommended a 25ppm Nitrogren fertilizer under the 5 day wet regime. If I were to switch to a 1 hour wet per day regime as I think you also recommended, would I use the same fertilizer concentration? Or am I misunderstanding your recommendation?
Yes.
I have found, in general, that most orchids do well when getting a 75-125ppm N solution weekly, so when I "fertigate" them as often as you, I stick to 25 ppm N.
