With RO water, Plagron's guideline is about 0.75 ml\/L for a starting EC of roughly 0.4, which stretches it to around 13,300 L. Mixing 500 L a day, that is close to a month of daily batches at the RO rate.\u003c\/p\u003e\n\u003ch3\u003eWhat's inside\u003c\/h3\u003e\n\u003cp\u003eA \u003cstrong\u003ecalcium and magnesium plant nutrient additive\u003c\/strong\u003e with NPK 5-0-0 and \u003cstrong\u003eCaO 5.7% \/ MgO 3.3%\u003c\/strong\u003e. The balanced ratio prevents calcium and magnesium competing for uptake. It is designed for RO and soft water, and for LED grows, where plants transpire less and so take up less Ca and Mg.
