CalMag Complete

TPS CalMag Complete by True Plant Science is an 80-90% organic calcium and magnesium supplement that contains nitrogen alongside its Cal-Mag profile — the distinction from CalMag OAC being the nitrogen content, which makes CalMag Complete more appropriate for the vegetative phase when extra nitrogen is beneficial. The nitrogen-containing formula supports both deficiency correction and general growth vigor during veg.

Being predominantly organic formulated, TPS CalMag Complete improves calcium and magnesium availability through organic acid chelation while also contributing to soil biology health. The product has a 18-month shelf life from purchase and should be stored below 75°F (24°C) away from direct sunlight for longevity.

Use during vegetative growth at regular intervals to prevent Ca/Mg deficiency proactively. Compatible with all growing media including soil. For flowering, many TPS growers switch to CalMag OAC to avoid the extra nitrogen during bloom. Works within the full TPS Nutrients system alongside Base A+B, N-Primer, and other TPS products.
