prob not him but you actually answered one of MY questions before i could ask! (had a slight amount of powdery mildew on one of my pot lips) time to raise the temp a bit!Some plant get powdery mildew at 70 degrees but that doesn't help you does it? Some plants are overfertilized at 200 ppm but that doesn't help you does it? I guess we don't know but that doesn't help you does it?
