Nitrogen ppm for different genera

[terryros]

Thanks. I think my problem is that I had about 10 years experience growing Phals in bark under lights a number of years ago. Now I am starting up again with a broader mix of things and using s/h. So, with new genera and new media I am not yet sure of what I should expect with some things right now. I am using 125 ppm N using Green Jungle 1-0-1 complete fertilizer (I support my local orchid green hourse) in RO water so the pH is good. I just thought that instead of waiting a year or so to see how things grew that I would try and optimize what I could right now. I guess I had just better keep doing what I am and see what happens.
