[APD] Re: Nutrient Dosing
"1) With relatively hard water (gH = 14), do I need to add MgSO4
(epsom salts) to my Fe/trace elements mix, or can I assume that
there will be sufficient magnesium carried in the water?"
Look up your local water quality report if available. Here's
A few excerpts for the Green Water Treatment Plant (GWTP)
(as CaCO3) 93
Total Alkalinity 66
Can some of the chemists here decipher what this means? I don't
add Magnesium, but should I? Sorry to co-opt your question, but
maybe a general answer will help us both.
"2) My newly planted H. difformis has white veins and rather
spindly new growth. The new leaves also don't have the deeply cut
ridges characteristic of this plant. I'm assuming Fe deficiency
here, since the iron was nearly undetectable when the plants
first went in. Current iron levels are at 0.1 ppm."
Sorry, can't really help. That doesn't sound like Fe. My h.
difformis started doing better when I cut back on K2SO4, but I'm
not sure of a connection.
