Hello all, I haven't had anything useful to add lately.However one of my friends temporarily had access to a spectrometer and has suggested to me that the formula for Dupla Drops ( the real thing) could be something like

N  Nitrogen      0
P  Phos           0.7 ppm
K  Potassium   0.1 ppm
    Calcium       2.0 "
   Strontium      0.1 "
    Iron          1180 ppm
    Zinc             0.2
    Manganese   1.5
    Molybdenum  0.2
    Copper          0.05
    Boron            2.2

I would like to hear how the above fits in with the observations and speculations so far.
