So Ive been having issues with a white powdery substance on my leaves for some time. I have sprayed the milk solution (1 part milk 4 part water + 2 drops of dish soap) and it has seemed to leave a white milky crust on the leaves. I don't know if its the mold coming back or the residue from the milk solution. Anyone have expertise in this area?
Pics may be necessary for a solid diagnosis. Sometimes powdery looking leaves is a symptom of Calcium deficiency.
Spray with Alkaline water. Either PH up or use Fiji water(its alkaline i've tested it don't ask..) What stage of growth are you in.
