Symptoms: The first warning of magnesium deficiency in plants is that the leaves are pale and not rich green. The primary way to detect magnesium deficiency in plants is to decide if the plant is suffering from chlorosis of the lower, older leaves. Chlorosis is a condition that occurs when a plant does not produce enough chlorophyll. Because chlorophyll controls the greenness of a plant’s leaves, chlorotic leaves are pale yellow or yellow-white. In some plants the leaves will curl upwards and may also turn red-brown to purple in color.

Full growing season symptoms include premature leaf drop, weak stalks and long branched roots. Conifers will display yellowing of mature needles, while with new needle growth the bottom needles will turn yellow before the tip needles.
