Thanks for the insight on
Botanicare calmag. Can you mention more about how you employ the Cutting Edge products? I found this note on their website about Plant Amp, their calcium product:
"** NOTE ** Plant Amp™ contains Organic Acids which cause a temporary low pH reading. Do not adjust pH up. The pH will rise naturally as the plant uptakes the chelated calcium in one or two days. "
Do you take this into consideration?
How about
Botanicare's organic nutrient line Ca and Mg supplements, 'Calplex 'and 'Huvega'. The calcium is derived from Ca carbonate, so contains no N source, and the Huvega from Mg Sulfate. (
CalMag plus uses Calcium and Magnesium Nitrate). The ratio of Ca to Mg in these organic supplements, if used in equal proportion, is the same as in
calmag plus (3:1 Ca:mg).
Gen Hydro product
CaMg+ is in ratio 5:1 of Ca:mg, and is derived from Calcium Carbonate, Magnesium Carbonate, and molasses. I have read and experienced that this product does not jive well with some other nutrient lines and is prone to taking things out of solution. Wondering if the Organicare or Cutting Edge would be better options with the Canna line, without adding unwanted N into the mid and later flowering phases.
Thanks for any thoughts!
