Funny. I just harvested a garden of outdoor cannabis. Cherry Pies, Blue frost, ect. My garden is surrounded by vegetation which by this time of year is nearly white from PM. Yet my plants have none, zip , zero, ect. Not a trace. At least not one visible to my naked eye.
I dont think it is the variety, rather the health of the plant, which dictates PM resistance.
I'm not suggesting taking the plants green. I'm saying the trees turn colors in the fall without a flush, and your plants can to! Lol do what works for you. It was just a tip. I know how my buds smoke and I have an excess of organic matter in my beds.

btw all that pm yo see on the plants around your garden that you are amazed isnt on your cannabis. its highly likely it cant be. there are other powdery white mildews all around and they can be species specific. for instance your cantaloupes covered in pm are probably infested with another species altogether and whe yours breaks out youll assume it spread. yet it didnt. happened to be favorable conditions around the same time as the powdery on you cannabis. its everywhere.
There are several species, that effect different plants!!! I would think it is variety that effects tomato.
my last post here on the subject... I'm referring specifically to organic farming. Nutrients are released by microbes that have a symbiotic relationship with the plants. These microbes feed off root exudates, as well as the organic matter in the dirt. If the plant needs more food, it releases more exudates to boost the microbial population, the microbes eat more organic matter, and then when they die, which occurs rapidly, the nutrients are made available to the plants. Plants can control how much food is available to them. Even stimulate specific microbes. Just because nutrients are in the soil doesn't mean they're available, which was evident on my soil test.
Sam is right in regards to temperature locking up nutes... Cold temps would decrease microbial activity. This can be used to our advantage in triggering scenescense without a flush.
Sam is also right about spores being everywhere. They just need the right conditions to germinate.
I choose eagle 20 over PM. I don’t care if its evil. IMO PM is more evil.
