Yes it is mildew the best way i like to get rid of it is to add some air rotation like a fan or some sort and watch my watering to much water can really be a bummer with high humidity.

I’ve seen this on my outdoor plants before. Not sure what it is honestly it i don’t believe it’s WPM- as I’ve run into that extensively indoor

Is this powdery mildew?
Is this powdery mildew? I am seeing some white spots starting to form on the underside and top side of lower fan leaves. Would adding an oscillating fan help prevent anymore white spots from appearing in the future or will I need to apply neem oil or something?

WPM
I found WPM on a few leaves. I was spraying spinosad at night. I stupidly thought spinosad would take care of that to. LED light showed much more PM but early stage. In A.M. sprayed 1tbsp baking soda, soap, veg oil per gal. Used 2 gallons. Will any of this interact? Thanks

White residue - Mildew or Sugar?
Plants are giving off strong plant like smell rather than bud smell. Almost chlorophyll or ammonia like. Is the white residue on the leaves signs of mildew or does it look healthy and it's just sugar?

White Spots on top of Leaves
I have discovered white spots on my plants. I think it is white mildew. From what I have read, the spores cannot be killed. You can only stop them a with pesticides or, if you are lucky, with a milk/water mixture, but you cannot remove them completely. What should i do?

Too little light
I have now tried removing the WPM by smiering 40/60 milk/water on the affected areas. Deep inside the canopy aswell since little to no airflow passes here due to the plant being so deep in the pot. And apart from that the plant recieves 8 hours of light and I cant install a LED.
