Fertilizer CalMag Pro
Plagron CalMag Pro fertilizer is designed specially for plants growing in reverse osmosis (RO) water and soft water. The fertilizer is designed specially to work perfectly with water hard or naturally soft. RO and soft water have virtually nil minerals; hence, plants often face a calcium and magnesium deficiency. Without these, their growth is very limited, cell walls are weak, and yields decrease.
The composition of Plagron CalMag Pro fertilizer guarantees a comprehensive supply of all the essential elements that plants require. CalMag Pro is the best ratio of calcium and magnesium, balancing mineral content in water and providing an ideal base to prepare nutrient solution. It will provide a balanced concentration of minerals while enhancing plant growth.
Balanced interrelationship: one product combines calcium and magnesium
Calcium and magnesium in many fertilizers often fight against each other, especially if they contain sulfates. In the case of Plagron CalMag Pro, these elements are present in the correct proportion so that they do not oppose each other and are therefore absorbed by the plant at maximum.
- Perfectly complements LED grow light – Calcium and magnesium are less efficient for absorption under grow lights. CalMag Pro compensates for this natural deficiency and provides for full nutrition, thus ensuring nutrition of plants under LED lights.
- Strengthens cell walls and increases resilience – Calcium fortifies the plant system, builds up cell walls, and enhances plant resilience to environmental stress, to pathogens, and also to physical injuries.
- Nourishes root development and nutrition absorption – Plagron CalMag Pro stimulates root growth and causes the fine roots (root tubers) to be better at absorbing vital elements from the substrate.
Composition
Nitrogen (N): 5.1% (as nitrate)- major growth promoter.
Calcium oxide (CaO): 5.7%- strengthens tissue.
Magnesium oxide (MgO): 3.3%- takes part in photosynthesis.
pH: 4.3 (adjusts solution pH to 6.0-6.5).
Form: Liquid; blue; odorless.
CalMag Pro Instructions for Use
Plagron CalMag Pro is very easy to use, but a few guidelines have to be respected in order for the plant to receive the maximum amount of beneficial elements. Before use, always shake the bottle so that the minerals are evenly dispersed in the liquid. Dissolve, at most, 1 ml of CalMag Pro per 1 liter of water (dilution 1:1000). Apply with watering every time.
You should dose CalMag Pro especially in the initial stages when plants begin to grow or adapt to the environment. It will also be useful later on, when root development takes place and when the first signs of deficiency appear on the leaves (yellowing or spotting). Use it in case your water is reverse osmosis (RO) or soft water, as you must fill the calcium and magnesium deficiency at the initial stage. Undoubtedly, this will prevent some problems from arising later.
The dosage is important to follow! High levels increase the salt concentration and burn the roots. Always measure accurately, follow the recommended dosage, and do not exceed it.
