I respectfully disagree, Sulfur is great for PM but he's already flowering.......that sulfur if used now will be in the weed and the taste is really unkind, lol. Ask me how I know ;)

I'd try the 60/40 milk treatment method at this point. Which is not usually a cure but it does fight it enough to get to harvest.

Outdoors sulfur is still safe at this point it will be washed off with rain

Yes the milk as a tool against pm would work great, add a wetting agent like yucca extract for best coverage. mode of action of milk is that bacteria will outcompete the other molds and the milks bacteria is 100% safe and also flower stage usable . Spray every 3-4 days and after rain storms

I think it's safe to add just a drop or two of plain dish detergent as a surfactant.

The rule with sulfur is you don't spray in flower. Period. Unless you want to taste it in your smoke. There is no way that rain will wash it off unless it rains right after you apply it. Once you put the sulfur on, the plant is going to continue to grow around those bud parts you sprayed. Then you will get all the way to the end of the grow and have nasty weed.
Use the milk or use some other over retail product to fight it back.

The Arbor is great as a preventative. Sulfur in veg is the way to go. I just started spraying my outdoor with sulfur twice before flower weather it needs it or not. Too late for sulfur now, and you'll be fighting a long battle with just the arbor. Grab a gallon of 500ppm hypochlorous acid. Cut it 1:1 with distilled water. This will kill any mold/mildew or virus on contact. Safe to use up until harvest. I just spritzed mine yesterday to combat some septoria.

They also sell generators for $14 so you can make your own with table salt and distilled water. I use my dehumidifier water.

You can use sulphur a few weeks into flower without issue. Especially outdoor.

Spraying silica can help stop pm from reoccurring. Make sure to spray only when it's dark or low light conditions. No full sun. There's a ton of different things you can do but you need to remedy the humidity first. Plants need airflow. If you don't do something to stop WHY it's starting on your plants it will just keep coming back, worse and worse as the plant weakens through the infection. Once you get big fat buds, and the weather switches to warm days cool nights and high humidity you're done-zo. You'll be tossing out more than you harvest, or you'll be smoking mold. Remedy the humidity, don't over water, use silica, spray with copper/sulphur, or whatever you choose.
Fyi, I've never had a plant totally recover from pm. It's always come back once it's started, and your plants are well infected now.
Good luck
