Hi Munki, sorry I'm a little late kicking in. Nice chop!!
About the PM issue. I finally found some Serenade(after all my plants are gone). Contains B subtillus, bacteria that kills PM spores, can be used right up to harvest and also can be sprayed on harvested buds to stop bud rot/PM. By the time they're cured the bacteria is gone.The bacteria dies off in 2 weeks and does not interact with human physiology. It has a bit of a smell but fades after 2 days and it should save buds from the cookpot.
I've recently seen it used and it kept PM from recurring for up to 10-11 days on a plant that showed spots every 4 days with other treatments. It doesn't seem to affect plant developement like most other treatments I've tried.(peroxide, skim milk, high ph water(not so much))
There's another product, called AQ10 I believe, that contains the same bacteria. Don't know if it smells any different.
Sorry I didn't bring it up sooner, but I couldn't find a source and didn't know for sure how well it worked. Maybe helpful in your next grow if you get hit with PM again.
Love the look of that drying line.
