i had a citrus plant for more than 2 years now, it has always been healthy but suffered last winter. so i decided to buy citrus plant "food" and administered this according to the instructions written on the bottle. lately, i noticed that the tips of the leaves of my calamondin plant are starting to turn yellow. does anyone here know what might have caused it? and what should i do next?
Your Citrus plant food contains the tree major fertilizer ingreadents nitrogen, phosphorus and potassim, and it also probably contains many of the trace minerals. However, rarely do they add magnesium. The leaf symptoms for magnesium deficiency is on OLDER leaves the lower center portion is green and the tips and sides become yellow. You can apply magnesium sulfate (Epsom Salts) either as a foliar spray or disolved in water and applied to the soil. 1 table spoon per gallon of water. - Millet
