The key is to get on it right away and stay on it. Lots of things will control it, but it comes back. Supposedly, meltatox will kill it, but is not available in the U.S .You can get it in Canada or Mexico.

Problem with Meltatox is its really toxic to humans and it can stress the plants. If you can get it try Nova powder.

So I had been noticing tiny spots on my Godbud plant (mostly in the lower leaves, many of which I plucked off), but I checked today and there are spots on my Juliet as well as my Strawberry Cough... they're small but they seemingly came out of nowhere sometime today, as there weren't any spots on the other plants until I checked them tonight after work.

Should I just try the milk/water solution and hope it stays at bay? I'm in week 3 of flower and they will likely go 8-9 weeks... I really don't want to use any more chemicals (I was using Neem and Safer soap for my mite issues but won't use that anymore), but I also don't want my whole crop lost due to this crap. Any suggestions beyond the milk/water or milk/baking soda spraying?

stumbleweed im fighting the same problem with my grow ive had it off and on just little tiny spots since week 1 from clone on atleast half of my plants.
man i used serenade last night and i can still see some so i dont know
that stuff really stinks too probly will not use it anymore cant be good for me to inhale
i soaked them in that stuff too
i think i am gonna break down and buy a sulfur burner since i am only 2 days in flower i think i will be ok
but i used neem oil 2 weeks ago so i think will wait until week 4 of flower what do you guys think?

I noticed PM shortly before I harvested my plants a few weeks ago - unfortunately too late to do anything about it. The problem isn't the worst I've seen, and the parts that don't have PM look great, but I certainly don't want to get myself or anyone else sick from smoking. The buds are now dry and curing. Is there any way to clean up the afflicted areas other than just trimming those parts off? Will any of the aforementioned solutions be effective after harvest? Ideas?

it's never too late to spray Greencure

When I pointed out to chimera that he was spreading false information I was deleted from his thread.

What you can do is take intelligent preventative steps.
Cleanliness is a must.
humidity and outside air are always a concern.

It all adds up to what we call "pressure". If your experience, in your room or area is that you have high pressure, I would use a product that is specifically targets to killing and preventing mildew. If you have low pressure, you may get by with these safe omri listed products that are much less effective.

Even though I grow indoors, I monitor my roses outdoors, since I bring in outside air to my plants. When I see mildew on my roses, I know conditions are right and there are trillions of spores about, and I need to be vigilant. Since i keep my room clean, and never introduce infected plants into my room, I am mostly concerned about outside influences.

soap and water kills mildew and their spores in low pressure situations. for high pressure situations I use Licensed Ag Products that all have about 18 to 21 days worth of protection. But even these will fail if your room is a breeding ground for mildew.

Retro is right. meltatox is good. Eagle, elite, bayleton rally and many others are good. and they should all be used in rotation.

Great thread. I had a bout with this monster recently and found these threads to be helpful. They are primarily about two different products-

the Zone/Penetrator combo

I bought the Z/P and it is working well for me so far.

Dammit, my problem has gotten worse.. I think I may have to chop my Godbud very soon and might chop the others as well, even though they're not nearly as bad. I just don't want them to get it as bad as the GB, which is getting covered in many bud areas (especially those under larger leaves). I heard someone suggest hydrogen peroxide at 20% to kill it right before harvest... What about GreenCure? I just want to get rid of as much of it as possible and salvage some of my harvest. The Cough and the Juliet have tiny spots and most of the main buds are totally free of it, but I'm just really paranoid about them getting it bad too in the last 2-3 weeks before they're done.

All except the GB have some cloudy and amber heads (ambers mostly on smaller trichs, the tall glandular trichs are clear-cloudy), so it won't be that much of a loss to pull them next week or something. I'm thinking of GreenCure as a solution for them and just nailing the Godbud with peroxide and maybe GreenCure also a day before cutting her down to get nuclear on the shit and hope it'll disappear as it's drying or something. What do you guys think, am I hosed?

There's a sure fire cure for the reproduction of Powdery Mildew on your leafs, run your room at 90F... I haven't done the leg work to figure out dirt yet and frankly this is all theory stage I am still buying shit... But hydro/aero is easy, keep your res at 60-65F and your room at 90F and you C02 at 1500PPM. (Dirt you should need nothing, just C02 and heat right??) Powdery Mildew should not be able to form on the leafs at 90F or more.

Now I am certainly no expert, and you should verify the numbers as in the survivability of your plants but I am thinking I can get at least 85F on plants I am growing with C02 without them even blinking and 90F should be possible with C02. (Even at 85F PM would struggle hard, PM like around 70F I believe)

Now two birds with one stoner, 60F-65F water temperature, a chiller will be needed here, is perfect to prevent fungi in the water, powdery mildew can not form on the leafs at 90F. Now the real kicker is... If you live where it is hot and you are cooling the room to the perfect temperature for Powdery Mildew to exist about 70F, that sucks you need C02!! But either way you chalk it up, you can use your lights hood air on a thermo to heat up your room even if you need to, you get 30-100% more yield from C02 supposedly and PM is f(ked out if it's share of your meds

Edit:
Here's some ideas I was throwing around with Cheap Hydroponics for equipment, the CHHC-4 is new I forgot the price... Call them for that or get it from where ever you do.. The original email had CHHC-1, but that is discontinued now. My setup has 2 x 20 gallons reservoirs, a separate res for the chiller a pump each to circulate the water between the chiller reservoir and the coils in each plant reservoir to cool them to 65F or 60F if some miracle I can hold that. Coils on ebay, everything else buy in one lump sum for a discount.

> CHHC-4 - (About 600 I think, it is new call him)
> Co2 Gen Propane GEN1 - $330 (pilot light) or $400 for the electronic ignition model
> ActiveAqua 1/4 Chiller - $410
> Durapump 600GPH (for chiller)- $31.50
