Canna pH Down
GROW - 38% Nitric acid solution. Like HESI, to avoid adding more phosphorus during the grow phase. Canna make a pH Down just for the grow phase with only nitric acid, so only adding nitrogen.
BLOOM - 59% Phosphoric acid solution.
'Organo' - 50% Citric acid solution. To avoid changing the NPK ratios of nutrient mixtures citric acid can be used to lower pH. The organic acid also maintains pH levels stable for longer. Relieves root stress and enables mineral uptake.
