My Kalanchoe needs help!! Dusty layer and dying leaves I left for 3 days & came back to this. It does get partial sun and I don’t remember changing anything. Few to consider: It is a couple ft away from my lettuce bed which is currently suffering from leaf miners & fungal gnats. Also, I might have put a drainage net at the bottom when I potted it. I water about every other week. There is a dust like substance that comes off powdery so definitely not wax. I seen online this could be powdery mildew but I want to make sure before i treat it. I’m thinking of trimming some bottom leaves because the top soil is nearly covered by its leaves. Originally by u/Content_While2068 on Reddit: https://tinyurl.com/28m6g44j
