There are no others, it’s literally the only plant in the building except for a tomato seedlingThey all have it. Once you can see it, its been around a few weeks

Mammoth cann controlWhat you spraying?
maybe because there's some truth to them...It seems like many newer growers are just focused on charts and measurements.
but it's only the end of its lifecycle when u see it....There are no others, it’s literally the only plant in the building except for a tomato seedling
Ya good luck once its started on a plant almost impossible to cure, But you can battle it to the Finnish an be fine if you stay on top of it, If the plant is in veg i would hit it with copper every 3 days for 10 daysMammoth cann control
Yes right before it fruits an spreads.but it's only the end of its lifecycle when u see it....
He's got Mammoth CannControl.What you spraying?
What do you mean hit it with copper?Ya good luck once its started on a plant almost impossible to cure, But you can battle it to the Finnish an be fine if you stay on top of it, If the plant is in veg i would hit it with copper every 3 days for 10 days
I'm sorry but i couldn't understand that, maybe i'm too highThankfully this is the only plant in this tent atm, there is a floor vent next to the plant with a fan pulling air out and there is a top vent open with air coming in
The ducting at the bottom is connected to an in-line fan pulling air out…the vent hole on top is sucking in air. I was thinking maybe I should bring the inline fan into the tent and pull air in through the top vent and utilize the carbon filter to filter incoming airI'm sorry but i couldn't understand that, maybe i'm too high
Can you please post a pic of the ventilation?
How about a citric acid spray, lower the RH, and increase airflow? I don't go by VPD either. Mine's always crazy since my RH is super low.The cause is spores finding conditions where they can colonize and multiply. At this point your best option is going to be using some kind of spray. Lowering your humidity is not going to get rid of it and can actually cause more spores to be released into the air.
I don't grow by any VPD chart and I've never had PM indoors in decades of growing. It seems like many newer growers are just focused on charts and measurements. A simple preventative spray of neem in veg would likely have prevented it. But that's just too simple.
Citric acid is too easy. Everyone wants some fancy commercial product that may or may not be toxic that claims it can be used up until the day of harvest and costs $45 for a 12 oz bottle.How about a citric acid spray, lower the RH, and increase airflow?

So I know that usually the exhaust is up too and the intake down low, but it was suggested me to reverse it due to heating issues in the winter where I am, it’s not as much of a thing now cause the season is changing, but it’s still in the 30s at night so it was helping keep my temps up, no smell or at least not that needs to be filtered yet, this plant was intended to be my mother plant…that’s kinda sketchy now.That should be vice versa.. The top vent should pull air out of the tent, the bottom should bring air in. Heat rises up, cold air goes down. And you don't really need intake ventilation, passive intake is enough through the opening screens on the bottom, so only the exhaust fan on the top should be enough. (although an intake fan is also good, nothing wrong with that, you can use it, but it should run slower than the exhaust fan)
The tent has to have a slightly negative pressure, the walls of the tent should suck in a little bit, not expand.
The carbon filter you should put on the exhaust fan on top, and pull air through it to remove smells, or push air through it if you have height issues.
For the intake on the bottom a carbon filter won't help much with mold spores and other stuff, it's mostly for the smell. And that would release carbon dust inside the tent. If you want to filter the intake air, use a HEPA filter (Xiaomi has HEPA filters shaped like a carbon filter, so you could attach it to a fan)
And you should place some small oscillating fans in the tent to blow on the leaves and mix the air around. Without those you will get stagnant wetspots and hotspots. Plants love a little breeze on them, makes it difficult for the mold spores and bugs to settle on the leaves, and it strengthens the stems. What is your tent size? Maybe 2 small oscillating fans in each corner diagonally, one below the plant and one above the plant.
And definitely few more hygrometers/thermometers placed around the plant. I have one on the bottom of the tent, one on top of the soil, and one on top of the canopy. And i'll add a 4th one just to have some in each corner diagonally.
