Hello there; I've had this Japanese Peace Lilly for more than a month now and it is starting to die, the edges started then the whole leaf gets yellow and dies. I keep it in a bright area(not in direct sun light), I fertilize with an NPK every 2 weeks. Does anyone have an idea what could be causing that? This is my second plant and I don't want to lose it as well. Any help would be appreciated. Thanks
Possibly salt injury from minerals in irrigation water and/or fertilizer as there appear to be salt deposits on the brown zone.
Do you think I should decrease the fertilizer concentration, or should I water with no fertilizer once or twice until the discoloration goes away?
Could be overwatering, or too much light as well. But I agree to much fertilizer would be my first guess. Id go once a month in summer, less in winter. More pics if you need more help.
