TG is the man when it comes to this kind of stuff so would have to defer to him 
. That being said...lol...I'd just go with a simple bacterial tea based on worm castings if you go nuking. In addition to what TG said to do it would only help. You need to get a small worm farm going at the least to make teas from for next year. That stuff would be chocked full of native micro cultures. Just filter the tea really well for foliar. Bummer about foliar spraying is you can beat up your bacteria pretty bad and peeps have tested this.
I worked at one health product manufacturer and we had an intestinal bacterial product based on cultures obtained from plant roots and plant leaves. Wild native plants should have a nice healthy symbiotic culture going...not something like sweet pea though. Damn PM AND thrips just love those things. I'd be tempted to throw some healthy native weeds in the brewer but never experimented this way though with foliar but prolly great for soil drenches. Feed weeds to your worms also. Weeds are awesome natural ferts and mineral rich.
As for calcium yeah I remember Tom saying that it's really key for combating both PM and pretty sure he said botrytis also. That stuff I gave you works great on PM also. It's great for everything...lol. One pumpkin farmer back east used a combo of that stuff and micronized calcium carbonate and his PM never came back. Calcium immediately deactivates the pectolytic enzymes produced by PM so it basically can not spread. I did a lot of research into CaCO3 and was gonna play with nano stuff that's man made so very consistent particle size down at .06 frikkin microns. I got some for a buddy to experiment with and was gonna use the 'stuff', BioAg fulvic and nano CaCO3 against PM but he never got to it. Smallest you can get natural milled CaCO3 is about 1 micron but even then the particle size is all over the place but still a very high percentage at the claimed size. It has to be like less than 5 microns to get into the stomata. I'd be a bit concerned about using the milled stuff cause the larger particles may plug the stomata.
If you play with fulvic I'd go with a foliar treatment also as it'll help. The stuff from BioAg rocks and some good stuff in there besides just the fulvic
. That personal project of mine seems dead but still a believer in that stuff. You still have plenty of time to treat a plant with a 1% soil drench then a week later a 1% foliar feed. Do a side-by-side with 2 matched plants. You might be surprised overall and should help against PM.
