Can anyone confirm if this is Powder Mildew?

[mackattack805]

Hey everyone, I have been wondering what this white powder(see photo) that has been building up on my plants was, and was wondering if anyone could diagnose for me. From what I can tell reading other posts on the forum, it looks like powder mildew which concerns me as I am in week 3 of flowering. The powder has been on the leaves for several weeks now without me thinking much of it, so if it is indeed PM I'm probably in for some difficult times. If it is indeed PM, it seems to be only infecting the Hindu Skunk plants, and not the White Widow plants which are in the same room. Can anyone tell me what I'm dealing with here?

yes. and its out of control. go get a pyrethran bomb and bomb your room \ or when you trim mildew spores will be flying round all over the place.


edit..
did i say pyrethran.. i meant fungafloor. i always use them as preventative measure... obviously the pyrethran would be for mites and other insects. lol

Looks like it to me and its everywhere.

yes. and its out of control. go get a pyrethan bomb and bomb your room \ or when you trim mildew spores will be flying round all over the place.

agreed

the whole room is infected now ,there will be so many pores in the air that the only true course of action is a total wipeout,remove all the plants and burn them DO NOT SMOKE THEM ,then sanitize the room completely,install a sulphur burner and run it with the room empty this will kill any remaining spores ,then start from scratch,dont accept clones unless u know the source is pm free otherwise u will just be back to square 1 ,,its a horid disease and very hard to eradicate ,,a preventive spray/dip using zone and penetrator helps through veg then sulphur burn as flowering starts to kill any spores ,other than that u just need to be vigiliant and pray

25% skim milk dilution sprayed on the plants might help. do it every 3 or 4 days, and get another fan in there to keep things dry. raise temps, and also try to dry it out in there with a de-humidifier.

thats what i would do. hot/dry=no mold/mildew. it also means no fungus gnats or fruit flies.

Actually the spores are probably around in all environments ....once they find a comfortable spot they begin to grow. Your room is badly infected. I would take everything down and run the sulphur burner in the flowerroom when empty then again in the veg room along with your veg plants.

and there should be a reason why you have PM

 

[chubbynugs]

PM in mj plants only can come from another mj plant. FYI strains of pm from other outside plants cant grow on your mj. So you got it from another mj plant somewhere down the line.

1) Spray plant with 1tspn of baking soda per galon of water.. (a water surfectant helps)
2) spray off with plain water
3) repeat, until all PM is gone
The baking soda acts as a pH adjuster, making the surface of the leaf inhospitable to PM... I would'nt chop down my ladies at all..

If baking soda doesnt work, try lighting an inexpensive sulphur candle, or 2...

WoW.... sure is.... just thought to ask? lol... yeah man, that shit is rampant around here. My buddy has it worse though, all he does when it gets like that is finish them up, and when you harvest to cut them at the base and run them under the shower and drench them b4 chopping them up... and shake them very dry!

 

[geopolitical]

Get a sulfur burner. It'll not only treat the plants, it'll nail all the surfaces that may have mildew spores on them.

 

[Just a nice guy]

for sure!


I would love to see a sulfur burner wrestle with that room!!!!!!!
Post pics b4 and after please!
(Im assuming you will be smart and get one)

get a fungaflor bomb at the grow chop and light it off. its like the pyrethrin bombs but attacks and destroys the mold spores. use it once and your powdermold will be gone. sulfer burners only change the surface ph on the plant and does not destroy the mold spores. fungaflor will destroy the spores and elliminate the problem. all other products on the market are to control powder mold not destroy it. just my two cents and im in cali home of the POWDER MOLD.

FLINT look it up

Completely wipe down the grow room with bleach and h20, then go and buy Zone + Penetrator and spray those bitches every 3 days, then after 1 month, spray every watering, I promise this works, you just have to be obedient and change some enviro problems, i.e. More air flow, no stagnant air...etc.
