Regalia is a strong biofungicide farmers use for a variety of reasons on cash crops. Not considered organic and is expensive. Don't want industrial chemicals on my weed.

IMO, its not the temps or humidity. its your fans; poor airflow. yes, there is 4 of them, but they are weak.

something like a 9" honeywell below canopy would be great (target, walmart, etc)
an oscillating fan up top is ideal. figure out how to mount it. or you could put all 4 of your clip fans up top if you get a strong fan for below canopy to save some cash for now.

airflow is a preventive measure, once you have PM spores anywhere on the plant, in the soil or in the tent /room, a fan is just circulating and spreading the spores. It's dust.

I am dealing with it indoor also with RH@30%. Once the "spores" get in the air they are difficult to eradicate. I have been diligent spraying every 3 days with Neem oil (dynagro), not the green oily crap they are selling on Amazon. Pure cold pressed Neem is considered organic, is tan in colour and solidifies at lower temps. Mix 1 oz. Neem with 2 qts. warm water and a couple drops of pure castile soap as emulsifier to mix. Spray all surfaces of leaves only, not developing buds with lights off. Soil can also be sprayed. I use a pressurized sprayer and shake contents a lot while spraying to keep mixed. It leaves a glossy shine on the leaves and inhibits PM growth on leaf surface. Once PM is already on the plant, you have the only option of garbage, not compost. Wash every surface of grow room with bleach or whatever to kill spores and start over. Do not dry PM pot in your house.

Low humidity is a pretty easy fix and one that will help keep pm at bay. If you’re somewhere that dry get an evaporative whole house humidifier. You can find em around $100 pretty easy. Your plants and skin will thank you.

I stand corrected. Still not certified organic.How much is it in CDN$? Some of these products aren't available in Canada.

After researching Regalia, it is OMRI and WSDA certified and reasonably priced, so again I stand corrected.

Not kidding about the skin either, I keep my house at 50-60rh year round and just don’t get dry skin or chapped lips.

Zinger our problem in Canada is that Regalia is not legal for sale in country.

To get it from the USA we have to drop ship, which is fairly straight forward but is an expense.

I figure that I'm paying $350 CDN for a gallon by the time it lands at my doorstep.

AirROS by Sage Industirals puts out Reactive Oxygen Species that kills PM in the air and on surfaces.

"AirROS by SAGE Surface & Air Purifiers utilize high voltage and high frequency-controlled pulses, but very low amperage to create non-thermal plasma and generate ROS (Reactive Oxygen Species). ROS are the sanitation/cleaning agents that prevent and destroy Molds, Viruses, and other Pathogens and control/eliminate Odor in the Air and Surfaces in two stages: "

How It Works - Sage Industrial

.

The AirROS and sulfur vaporization are the two best ways I've found to eliminate PM, I like the AirROS better.

I'm no chemist but high voltage plus ambient air equals ozone, how they work peroxide into the equation is beyond me, but results speak for themselves. Thanks.

Regalea sounds great but wow it's pricey. Guess it's worth it to save product.
I went in to cull and clean the tent out and couldn't do it lol, got too sad. Interrupted the night cycle too :)
That airos thing has a request a quote... yea I definitely can't afford that haha.
I live in marshlands so I think the air here must be like 10% PM?
Posting some pics from just now to show how the ventilation is set up.
Also got the ac infinity fans in and they don't oscillate... those aren't out yet :(
Any better fan options than what I have that will fit such a tiny space? Should I grow less plant?
Very bummed and very stoned
Thank you all for your help so far!

Last year was bad outdoor for high humidity at bud time and mostly everyone was touched by it. Had to cut early after nearly stripping the plant of leaves in early September. I loose sleep over this shit! Bugs are one thing but indoor PM is a bummer! Cleanliness in grow room is essential, don't introduce anything from anywhere into that clean space. I get lazy and instead of preventive I get reactive but your grow looks fine other than ...
