In plants, it represents a building block for chlorophyll (leaf green), and therefore, it is essential for photosynthesis. At the same time, magnesium plays an important role in the energy transfer. Together with calcium, it is also a component of tap water, influencing water hardness. Inorganic magnesium fertilisers are produced using the same bases that are used to produce potassium fertilisers.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"introduction\"\u003e\n\u003cspan style=\"color: #000000;\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003ch3\u003e\u003cspan style=\"color: #000000;\"\u003eABOUT MAGNESIUM IN SHORT\u003c\/span\u003e\u003c\/h3\u003e\n\u003cdl\u003e\n\u003cdt\u003e\u003cspan style=\"color: #000000;\"\u003eWhat is it and what does it do?\u003c\/span\u003e\u003c\/dt\u003e\n\u003cdd\u003e\u003cspan style=\"color: #000000;\"\u003eMagnesium is indispensable to plants\u003c\/span\u003e\u003c\/dd\u003e\n\u003cdd\u003e\u003cspan style=\"color: #000000;\"\u003eRepresents a building block for \u003ca class=\"glossary-link\" href=\"http:\/\/www.canna-uk.com\/glossary#chlorophyll\" style=\"color: #000000;\"\u003echlorophyll\u003c\/a\u003e \u003c\/span\u003e\u003c\/dd\u003e\n\u003cdd\u003e\u003cspan style=\"color: #000000;\"\u003eIs essential for \u003ca class=\"glossary-link\" href=\"http:\/\/www.canna-uk.com\/glossary#photosynthesis\" style=\"color: #000000;\"\u003ephotosynthesis\u003c\/a\u003e.\u003c\/span\u003e\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003cdl\u003e\n\u003cdt\u003e\u003cspan style=\"color: #000000;\"\u003eWhat do you see?\u003c\/span\u003e\u003c\/dt\u003e\n\u003cdd\u003e\u003cspan style=\"color: #000000;\"\u003eRusty brown spots\u003c\/span\u003e\u003c\/dd\u003e\n\u003cdd\u003e\u003cspan style=\"color: #000000;\"\u003eCloudy, vague yellow spots between the veins.\u003c\/span\u003e\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003cdl\u003e\n\u003cdt\u003e\u003cspan style=\"color: #000000;\"\u003eWhat can you do?\u003c\/span\u003e\u003c\/dt\u003e\n\u003cdd\u003e\u003cspan style=\"color: #000000;\"\u003eSpray with a 2% solution of Epsom salts every 4-5 days during about a week.\u003c\/span\u003e\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003cspan style=\"color: #000000;\"\u003e\u003cimg alt=\"infocourier-magnes_text_4.jpg\" src=\"http:\/\/www.canna-uk.com\/sites\/default\/files\/images\/growinfo\/default\/infocourier-magnes_text_4.jpg\"\u003e\u003c\/span\u003e\n\u003cdiv class=\"specialbox1\"\u003e\n\u003cspan style=\"color: #000000;\"\u003eSYMPTOMS OF A DEFICIENCY\u003c\/span\u003e \u003cspan style=\"color: #000000;\"\u003eWhen there is a shortage, the leaf green in the medium-old leaves under the flowering top will be broken up, and the magnesium will be transported into the young parts of the plant.
