SHOGUN Calmag offers a highly refined source of Calcium and Magnesium for your plants. Calmag is an essential addition to your feeding regime. Aside from deficiencies Calcium and Magnesium offers and huge range of benefits to your plants, it is often an overlooked addition to any feeding regime that can create huge improvements. Calmag actively enhances your plants ability to transport and use other essential nutrient elements around as well as helping to facilitate many of the plants essential functions.
Benefits of Calcium and Magnesium:-
Magnesium plays an crucial role in photosynthesis by assisting the production of chlorophyll, Magnesium is the powerhouse behind photosynthesis in plants. Without Magnesium, chlorophyll cannot capture light (sun,bulbs, lamps) energy needed for photosynthesis. In short,Magnesium is required to give leaves their green color. Magnesium in plants is located in the enzymes, in the heart of the chlorophyll molecule.
Calcium is a great additive to use not only to prevent deficiencies, but also has other benefits such as aiding your plants overall performance and improving your plants uptake of vital elements. Calcium is responsible for holding together the cell walls of plants. When calcium is deficient, new tissue such as root tips, young leaves, and shoot tips often exhibit distorted growth from improper cell wall formation.
Many growers notice a change in leaf colour leading them to need a 'Cal-mag' suppliment to restore the plant back to good health. Things to look for, especially during the flowering phase is a change in leaf colour. When a Magnesium/Calcium deficiency is present the leaves show visible rusty brown spots and/or vague, cloudy, yellow spots between the veins. The older, larger leaves just above the bottom/lower leaves will show the first symptoms. Yellow/brown spots occur, which are often surrounded by a sharp brown outlined edge. In addition, the growth is curbed and in serious cases the tops are smaller than normal and do not close. A slight shortage of magnesium/Calcium hardly affects flowering, although the development of the flowers makes the deficiency symptoms worse. Signs of a deficiency are likely to first appear around the 4th-6th week. The colour of the young leaves and the fruit development are not affected. You may notice the size and number of rust-brown spots on the leaves increase, then symptoms spread out over the whole plant, which looks ill. When the shortage of magnesium takes ovee the younger leaves are also affected and flower production will be reduced.
Reasons for a deficiency
The magnesium deficiency can occur because uptake is inhibited because of:
- A very wet, cold and/or acidic root environment.
- A high quantity of potassium, ammonia and/or calcium (for instance high concentrations of calcium carbonate in drinking water, or clay soils rich in calcium) in comparison with the quantity of magnesium.
- A limited root system and heavy plant demands.
- A high EC in the growing medium, which hinders evaporation.
Calmag can be used during both the vegetative and flowering stages to combat this deficiency, but prevention is better than cure therefore using Calmag alongside your base feed will assist with keeping your plants healthy and disease free. Shogun Calmag agent is also used to raise the Calcium/magnesium content which will raise the EC Levels of your water and you will then be likely to require less base nutrients.
Root Feed – Add at a rate of 1-2mL/L to your nutrient reservoir or watering can. Use throughout vegetative and flowering growth.
Foliar Application – CalMag can be used as a foliar feed to correct deficiencies relating to poor establishment or environmental problems. Add at a rate of 15mL/L and spray onto the leaves. Spray once per week until the issue is resolved. The recommended pH for foliar application is – 5-7.
