I just took some cuttings 2 days ago, and they are in the humidity dome. The cuttings were put in Olivias cloning gel, then placed in rooting plugs. This morning I went to check them, and there was a powdery substance I was able to wipe away, on some of the plugs, but not the cuts. The cuts are isolated from the plants, and the room temp where they are is 72, with low humidity, but I am not sure what the humidity actually is. So is this the beginning of powdery mildew. I am brand new to growing, so I am so stressed right now. I have not wanted to inundate myself with information about it, so I have tried to not read about it yet, but I know it is a game breaker. I can't even take a pic, cause I dropped my digital camera into a home depot bucket full of water, yes I am a dumbass!!!! So please somebody help this dumbass newb, before I have cardiac arrest from stress...thank you in adavance!!!!! If this is indeed powdery mildew, and I only see it on the rooting plugs, can these new cuts be saved and still root? Is there a wash I can use, or can I spray a hydrogen peroxide mix on the plugs? I only see it on the plugs, and have wiped it away with my finger. Thank you for any assistance.
