Nutritional Issues
One common nutritional issue in poinsettias is magnesium deficiency, which can occur when using 20-10-20 fertilizer in areas with low magnesium levels in the water source. As
the Mg contribution from any dolomitic limestone leaches out of the pot over time, the deficiency can easily develop.
