Rectify nutritional imbalances and fortify your crop against hidden deficiencies with Plagron CalMag Pro. This professional-grade mineral supplement is explicitly engineered to step in where soft water sources and Reverse Osmosis (RO) filtration systems fall short on essential calcium and magnesium levels.

As indispensable secondary macronutrients, calcium and magnesium play a pivotal role in sustaining your plant's internal infrastructure throughout its entire life cycle. CalMag Pro serves as the perfect remedy to stabilise your background water parameters, resulting in drastically strengthened cell walls, heightened stress resistance, rapid root development, and vastly improved macronutrient absorption.

Core Cultivation Advantages:

Optimised RO and Soft Water Treatment: Provides the ultimate buffer for growers working with pure RO water or naturally soft tap water, safely elevating the water's background mineral profile without causing nutrient lockout.
Cell Wall Fortification (Calcium-Driven): Calcium takes centre stage during the vegetative growth stages. Much like silicon, it directly fortifies cell walls to support heavy, rapid growth, sturdier plant structures, and optimal nutrient transportation channels.
Photosynthesis Optimisation (Magnesium-Driven): Magnesium is the fundamental central atom required to construct the chlorophyll molecule. Chlorophyll gives your crops their vibrant green colour and drives the photosynthesis process, enabling plants to effectively convert $CO_2$ and light into active growth energy.
Balanced Mineral Foundation: Delivers a concentrated 5-0-0 NPK foundation alongside highly bio-available percentages of Calcium ( $4.1\%$ ) and Magnesium ( $2\%$ ), ensuring your plants stay pristine and free from leaf rust spots or yellowing.

Application Timing & Dosing

CalMag Pro is highly versatile and can be utilised either to create a standard background water base or as a routine preventative supplement:

Application Strategy	Target Target Parameter / Rate	Application Frequency
RO / Soft Water Buffering	Add until water reaches 0.3 to 0.4 EC	Use to treat your fresh water before adding any other nutrients.
Routine Preventative Feed	1ml per 1 Litre of water ( $1:1000$ )	Apply to your nutrient reservoir during every single irrigation session.

Step-by-Step Usage Instructions:

1.Shake the bottle thoroughly:Agitation.

Before measuring out your dose, shake the CalMag Pro container vigorously to ensure all dense calcium and magnesium elements are completely redistributed for an accurate mix.

2.Add CalMag Pro to your fresh water first:Water Buffering.

Always add CalMag Pro to your fresh water tank before mixing in any base feeds or boosters. If using RO or soft water, use an EC meter and mix in CalMag Pro until you reach a stable baseline of 0.3 – 0.4 EC.

3.Introduce your primary feeds:Base Integration.

Once your background EC is securely established, proceed to add your standard vegetative or flowering base nutrients (such as Coco, Hydro, or Terra lines) and stir the tank thoroughly for 10 seconds.

4.Check your final parameters:Final Verification.

Use your calibrated digital meters to check the overall EC and pH values. Calibrate the fluid back down into your substrate's ideal sweet spot using Plagron Lemon Kick if necessary, then irrigate your crops.
