Hey, for what it is worth. I have seen recommended using a couple of things for PM with each other. I just had some. So what I did. First i actually used some lactobaccilus mix spray for a week. I did the baking soda water for next week. And more I used a 20 to 1 water and apple cider vinegar mix the following week.
I also have some sierra natural science 244 should be here today. Sierra Natural Science SNS-244 Best for Powder Mold
Also i used the spray stuff at light on or just before. to help keep the humidity down during lights off. All the feecking cold wet with the snow and it rained buckets last night I hope I can keep it gone. My little city apartment prolly has all sort of mold. You would think the car exhaust would kill it but nah.
I hope it isnt PM for ya BAR.
For PM, I'd try potassium bicarbonate. I have some but haven't needed to use it yet (knock wood). Check it out. It sounds like it is the most effective stuff you can use that is both safe and inexpensive.

Wow! The new photo uploader is a whole lot of unnecessary nonsense. Anyway...
Thanxx Pita & Mr. Blue
The deed was done before I left home this morning.
A look at the last 24hr conditions and the environment at lights on in the Big Tent...
AFGHANI KUSH
I mixed the baking soda & h2o and removed the moldy fan leafs.
Before
After
I sprayed and shook off the excess mixture before placing her back in the tent. This evening right before lights out I'll spray the whole tent for preventive maintenance.

Reg, with as many plants as you grow and as nasty as PM is, I'd cull that beatch and burn her.

I'm so scared of P.M.
I'm currently experiencing 70% R.H. in my closet that is VERY crowded right now. How worried should I be?

Worried enough to source some potassium bicarb.

I think my parasympathetic nervous system just kicked into gear. I'm feeling the anxiety wash over me.
I have been training my plants for a long veg and they are pretty big now. Wondering if I need to grab a 400w HPS or something and split the plants into two spaces.

Whats up Bar. No snow are way, just strong winds us 
Good catch on the mold spots, we dont want that spreading 
love the way uv just straight reused that pot for this plant, i need to start doing something similar.
Nugwrasslin If ur plants are in veg thats RH is ok. but for flower u want it down 15-20% at least. mine changes from 90% to 40% RH, i never have big issues. But when lights on it stays at a 50% mark. If u add a dry towl or the likes for the time, to keep any major moisture down. Good luck

I really appreciate the input dudes. I was getting like 10-15% runoff and letting it sit in this little black tray I have below my plants. Going to try and plan my waterings to more like 1-5% runoff. And throw a towel in there for sure as well. Thinking about getting another fan too.
I've had RH at 90%+ in veg with no problems. I don't recommend it, but as long as the spores don't find your room, you can get away with it.
It is frustrating for me since my RH is usually way low in veg, but when the plants get bigger and flower, the added transpiration keeps the RH too high. Other than a few weeks right in the middle of a grow, it seems like I'm always fighting RH, trying to raise it or lower it.

I feel ya Pita... It's to low in the veg tent and to high in the flower tent... I tried swapping them out thinking it was where the tents were sitting n the room... Na not that easy.:

Sorry to hear of your PM BAR. I think I PM'd you about the PM, after this post here.
If I had to guess, you sprayed your plants with Snowstorm, with less than perfect ventilation and circulation (super important). RH in the ranges you have been, is probably less important than circulation/agitation, so that is most likely your culprit.
I would not increase circulation (direct fans on plants) until you have cleaned the infection, or you will just spread the spores. Several ways to clean it, I'm sure you'll get some good advice here from others too. You can cull the plants. You can strip the bad leafs, and clean them in the tub. If your city water if it's buffered high like mine (9.3), it is also helpful as an antifungal. Even better when you mix something with it.
I'm not sure how you feel about it, but I've torn down everything when I get PM. I mean literally everything. I'll wait for any good plants to finish though. It's a constant battle for me, but with intense air circulation, I can weather 70+ RH for the last couple of weeks of flower, and not find a single spore under the scope.
Cut the foliar feeding or spraying (except PM treatments), Snowstorm included, until you are certain you have perfect ventilation. Work on adding more fans, and air exchange. Sorry to hear my man.

Pita, we usually don't toss anything but males. But then again....
Nugsy, now you guys have me scared.
High Indo. Thank Woody & Carestaker for catching it on a previous harvest, Pineapple Chunk. I've never dealt with nor had any idea what mold looked like at the time but now it all makes sense. Spraying the "Snow Storm Ultra" on the PC every other day most likely caused the outbreak. Since the Afghani Kush was next to her the spores traveled.
There were 2 plants in that pot but one was a dude. Hence the stump.
No nutes but thanxx for the heads up B Really Real. We're growing in PJ's OSM; just add water. Is too much fert another path to mold?
Yes you did Carestaker...
How often should I spray the Baking Soda Mix and for how long?
This evening we'll be emptying the tent and wiping it down with a mild mixture of soap, bleach, and water. Should I add a little baking soda to the bucket?
everyone for getting to the bottom of this mess quick fast. After I'm sure the Big Tent is mold free we'll resume the 3 tent rotation.
If you use bleach, I don't think BS is necessary to wash down the tent. It won't hurt but...
The big issue will be getting rid of spores on anything that goes back into the tent. That's where the PB works best, IMO.

I remember reading this cause my city water is like 8.9. I guess mildew doesn't like alkaline conditions.
I used the baking soda and what not while the stuff was still in the tent to spray the pots and wipe any surface or what not but didn't feel like it was complete. So I took everything out and wiped with a mild bleach solution, clorox or some shite i forget. I still worry i missed something. I got a little more air flow in there as well.
good luck
Hey BAR. 
I don't have a lot of experience cleaning the infections on plants. I don't want to coat my plants with sulfur, so I'm limited to a few options. I'd just pluck the PM off, or cull the plant entirely depending on severity. PM is systemic, so even if you don't have any on the outside, it's still on the inside, just like a ticking time bomb. PM from cannabis is specific to the plant. You have to kill it all.
My advice, as tough as it sounds, and for what it's worth - is to assess your girls in flower, and finish the ones that are close - and cull everything else. Tear every piece of equipment down, and clean everything with a light bleach solution, especially every tent's outer fabric - mist the hell out of it. Clean the entire house, all the hardwoods, everything - with antifungal sprays. I use bleach on the tents and equipment, and the SNS-244 anti-fungal spray everywhere else around the house, and mist almost everything. It smells like what it's made out of - Thyme, which is strong for a little bit, but then disapates.
It's only by doing that, and adding multiple circulation fans to my tent, that I've remained PM free.
I usually have 2-3 of those turbo fans pointing up at the plants from the bottom, and one on top - in addition to a 6" high output extraction fan in a 4x4. You've done real well to be growing as long as you have, without learning of this pestilence.
When every leaf in your tent is moving almost constantly, you've got enough fans. Beware too, when your lights go out. As temp drops, if there is a big swing, condensation will form, as there isn't enough temperature, to hold all the water in the air. Your extraction fans really need to be on high, and your circulation going too, if this ever happens in your grow. Also, prune all growth close to the pot, it's like a stepladder for mold. I'm sure there's more, but there's some actual pros in here that can speak to this better than I. Might you document your way through it ?

Correct, it is pushed high with buffers to make it inhospitable to fungal propagation, which enables a reduction in the amount of Chlorine and Chloramine needed to ensure potability. There are fish tank treatment drops that will help neutralize the Chloro components. Stress Coat and others.
