Just that in my experience my plants have never really needed that much kno3 / po4, something more like 20ppm for kno3 and around 1ppm for po4 is more what i go with, in the past (before using RO) with high levels of both, growth was never its best. Yea, the Salvinia could easily be using up your k too.
Looks like you just have to try a few experiments out to get the right levels, but i doubt the light is the issue here
