Magna Marta Cal Mag is known as a secondary nutrient as plants need them in smaller quantities. As LED’s are becoming more popular, we are seeing the need to add Cal-mag at the top end.

Magnesium is in the heart of the Chlorophyl molecule, it is what helps drive photosynthesis in plants, without it plants cannot capture the suns energy needed to produce Glucose. Magnesium gives plants their lovely green colour and is also used to metabolise carbohydrates while stabilizing the cell membrane.

When plants have deficiencies in magnesium it can be caused by high levels of potassium, this leads to the plant absorbing the potassium and leaving behind the magnesium. This will show on the older larger leaves first as a yellowing between the veins and around the edges this then leads to brown patches which then leads to the leaf dying off. Calcium is also a secondary nutrient but like magnesium is an essential part, mainly through the growth stage of the plant, Calcium helps build strong stems and leaves helping with symmetry of the plant.

Usage:

• Grow Stage Week 1 till flower – 10ml/10L

• Flower Week 1 till week 6 10ml/10L

• Flower Week 6 & 7 5ml/10L

Benefits

Nitrogen, Calcium and Magnesium supplement for use in environments or substrates that require increased content, or for use to correct deficiencies as they appear. This formulation has added Chelated Iron which aids in the production of chlorophyll and will lead to better uptake & availability.When chlorosis is present (yellowing) the most immediate way to correct this is through foliar application. If in environments with elevated rates of photosynthesis due to Co2 or LED usage, add at the top dilution rate as standard.
