TNC CalMag is a liquid concentrate containing calcium and magnesium which can protect your plants from symptoms of deficiency in both these elements. Calcium is an essential mineral used in the production of new plant cells. It is not mobile within the plant. it is conducted up from the roots by the xylem and if it is not available on a continuous basis, new cells cannot be created. If it is in short supply it is evident when new growth (the part of the plant furthest from the roots) fails to develop properly and either curls or dies. It is referred to as leaf tip burn, blossom end rot etc. Magnesium is an essential component of chlorophyll which is used in the process of photosynthesis and which gives leaves their green colour. Yellowing between the leaf veins indicates a lack of magnesium.
