Discoloring or mold?
All my plants keep getting this on the surface i think it may be fungus or mold it goes away for the most part when its time for the plants to be watered but then comes right back. The ones which get the most light seem to be worse. They are all growing but its disgusting looking and i want to make sure they are not going to be affected. If it is mold or fungus how can i treat it?
