Since youre only a week into flower what if you set the light back to veg and spray then go back to 12/12 in a few weeks?
@JoeCrowe would the buds still taste like sulphur in this case?

Started them from seed.

When did the infestation start? You had it before?

Never had it befor, and I just noticed it yesterday.
I had a hermie last run so cleaned everything very well.
the only thing I can think of was something in my pre made soil 20 gal tote that was sitting for a couple of months, I had it moistened from the last grow and just used that.
as well. 2 fabric pots I didn’t give them a good run through the washer. Just a quick rinse and reuse.
I believe there are a couple of ways this entered my tent.
laziness being the main reason. Can’t let your guard down. Once again, finding out by failure 
Yep, name checks

Southern AG Garden Friendly Fungicide and Azamax are what I use to prevent/control PM. I include those in my spray mix during veg and all the way up until when buds start forming. Then, it’s fingers crossed until harvest.
Last chance to apply would be 2 to 3 weeks after starting 12/12. Azamax is derived from neem oil, and it will make the buds smell/taste funny if sprayed directly on buds. GFF is a biological solution made from a strain of bacteria.
They should not be applied if you are using sulfur.
Only apply after sunset or lights off. Otherwise, it will burn the plants.

Thanks for the info Tracker.
But I think I’m just going to cut my losses.
Toss everything, fabric pots. And a bit of promix that’s been sitting moist for a couple of months.
I want this gone forever and don’t have the patience to fight it for what might be shit to smoke.
I needed a new bag of promix anyways. And I got plastic pots as well. Or just go by a couple of geopots.
Ps. Just posted on your thread about this

You can never get rid of PM. There are always spores floating around in the environment. When they find the right temp and humidity conditions, they start growing.
Only thing you can do is maintain warm/dry environment and apply preventative sprays.

Great info and thanks Tracker and Joe 
A couple of questions.
So knowing that, should I also replace my air filter as well?
A year and a half of growing, I know that’s not much. But I always started fresh for each run. Except this one. I got lazy and cheap and I am paying for it lol.
Im cool with failure as long as I learn from it.
So trying to wrap my brain around what might of caused it is driving me bonkers. 
Do most people use the sulpher spray during veg?
I guess not. Until the open their tent and see that nasty shit.
I guess I’ll start using it in veg going fwd to make sure this doesn’t happen again.
Also, what do I use to wash up the tent walls hydrogen peroxide straight up or diluted, or IPA?
Thanks fellas

Cleaning and disinfecting your tent won’t prevent PM. The spores are everywhere in the air. If you are running environmental controls, stay on the warm/dry part of the VPD chart with plenty of air movement. Apply preventative sprays.

Sounds good. Glad I got 2 days off work.
Now… What to pop next

This is on point…I would say keep humidity in control …when it’s monsoon season and R/H is above 85% I start getting mold even on clothes in my cupboard and they go as soon as monsoon is over and the air gets dryer.

Ohhh shit! Did someone fire up the misinformation train? Killing mildew off is easy as pie. Definitely not related to VPD at all. There are no “spores” in your air filters, on your shoes or in the ventilation ducts. It’s an obligate biotrophic ascomycete. Once you understand it’s life cycle it’s easy to extinct. The infection is brought in on infected plant material, and it regenerates the colony from the fallen bits of plant material on the ground.

Maybe I’m confusing PM and normal mold.
Apologies just trying to learn …lost 5 months work because of high humidity

Yah high humidity will lead to botrytis cinerea, aka Grey mold or Bud rot.

After reading this, I think I know exactly where it came from. The 2 fabric pots I didn’t wash were nasty. Sitting together, damp for a couple of months.
I just did a quick rinse of them, and threw em in the tent.
So going forward, new fabric pots every time. $3 each. I can handle that.
As well gonna grab a shop vac to suck up the run off, I’d been letting it sit in the collection trays and letting it just evaporate.
.
So I’ve popped 3 meatbreath from @Wizdom and 3 walkinstein from @JohnnyPotseed for my next attempt. 
2 failed grows in a row does a number on your confidence. But I ain’t giving up, eff that.
With that being said, @JoeCrowe I’m kind of a simpleton when it comes to all the crazy pathogens out there.
What would you do, clean the tent like you would after a normal run, or is there anything different I should do before putting anymore plants in there?
Super appreciated all the info, I think we’re all learning as we go along in life @globalhead
Accepting help, and learning is all part of life. So many people are scared to admit when they need help.
There is such an incredible relationship between us and these plants that can be translated into life in general.
It’s made me a better person all-around dealing with issues with others and with myself.
Sunday… Deep thoughts by Lz

Yah toss the plants in there and then once they start to grow, spray them twice with sulfur mixed with water. The mix is 1 tablespoon of 90%+ sulfur in a liter of water. Half that strength will work. Spray the plants and then again 2 weeks later. The mildew will be dead and then you just keep growing from there. The mildew won’t come back.

i have NEVER had issues with PM here, and i think that is due in part to the hot/dry nature of where i live.
i HAVE had to battle botrytis (bud rot) my first year, but that was all n00b mistakes. (i wasn’t shaking the rain/excess water off the buds during the tail end of flower.) i lost several plants in that learning process.
most of the molds/fungus require a LOT of humidity to prosper. your tent might be holding in more moisture than you think. do you run humidifiers? they may be depositing too much moisure.
also increasing ventilation (more fans?) would help reduce the risks.
there are several methods and products that will kill off the PM. you do not necessarily need to cull your crop, as you might be able to salvage with the proper care.

Perfect, thank you very much 
BTW love the work you put into all the lill microscopic enemy’s. Some interesting information in your threads, and incredible pics. And the live resin, oh my.

I did switch to a cheaper ACI air filter. It’s smaller, so at the same speed the older larger air filter probably moved more air out. Something else I didn’t take into account. So many variables, I think I just have it the perfect environment for it to take over.
I culled em last night, and will start fresh. I’m a bit choked. But look at all the knowledge I’m getting
I’ve got 2 6" osolating fans, and 1 6" hurricane fan on the floor bringing in fresh air, it’s in front of an intake. As well an oil heater in the tent always on high, getting it up to 75ish to 78ish.
Don’t know what else I can do for air movement.
my humidity never went above 80, I didn’t notice any in veg, it only appeared in flower about a week I and my humidity monitor was around 60 for the entire week or so in flower.
So that’s why I’m thinking it was the bags, I brought it in with them, and gave it the perfect environment to grow… See I’m good at growing… Anything… Haha

that is entirely possible/plausible.
i wash all my stuff with bleach after use. i have never used fabric pots, but they certainly do seem like they would be a good incubator for molds.
