Default Is this Powdery Mildew

I am assuming this is, not quite sure, this is only showing up on the plants that are in veg room, scoured the flowering girls and saw nadda on them so far. I hear Greencrue is suppose to be da bomb.

so shall I toss all of them that have it, I have already cut off the parts that had signs and tossed them. I have been reading found an abstract about using mono-potassium phosphate as a foilar spray could this be considered a systemic cure for PM
http://www.sciencedirect.com/science...b18fd1f5f5342b
also thinking of getting some UV-C lights they are supposedly the germicidal UV light

Sm90, DM Zone and Penetrator, Canadian Xpress PMT are all good preventative and controlling treatments.

There is essentially NO systemic PM killer that works with Cannabis. I have researched loads on this as I recently had it.

Firstly, dispose of all plants in the room. It is likely that ALL your plants will now have PM.

Then strip the room, clean everything and rebuild. Burn a sulphur candle . Also address your ventilation and air movement. Lack of good airmovement and recirculating air is a big cause as is wet conditions and massive temp differentials between night and day.

And from then on I would suggest a weekly spray with PMT and you should then be fine.

IMVHO, PM is about as bad as infestations get. Mites are an absolute doddle compared to PM.

I wouldn't throw away a girl because she gets PM. Is it really so dire? I've seen a lot of people post how the Sweet Pink Grapefruit is susceptible and I know some people cull it. I also know theres a bunch of folks who cherish her.

I think you can grow a plant to help itself. What Tehherb says about temp fluctuations seems a likely culprit. At least that's what I've experienced too. What temps were you guys reading when your girls went down? Were any of you using preventative sprays at the time or was that how you learned?

I can't stand PM, I would agree with herbalizor that mites are easier to deal with from my experience.

The number one thing is to make sure your environment is as hostile to those spores as possible. Dehumidifier, sulphur burner, greencure, and make sure ventilation and airflow are on full-tilt. If you have some money, grab a nice HEPA filter and throw that in there too.

If u really love your plants and dont want to get rid of them here's what i bought on advice from keyplay dude know's his stuff and i havent seem pm since i bought this stuff

I Feel your pain, brother. You are really too late in the game to alleviate your PM problem completely without screwing up your flowers. PM is systemic, so its in the plant. It might have been there before you flipped.

Banner Maxx is a excellent source for prevention and irradication:
http://rosemania.com/shopsite_sc/sto...product72.html
Do a run off in your 2nd or 3rd week in flower using 1/2 tsp per gallon. This will kill the bad pathogens in your plant and you will not have any problems throughout the rest of your cycle. Use protective gear!.

Try Quantum Growth for excellent results:
http://vitalorganisms.com/products_quantumgrowth.html
I mix 15 ml of Quantum Growth with the Banner Maxx and a drop of dishwashing detergent. Killer results! Microorganisms to the rescue as a back up.

Default Loaded the arsenal

So because I hate this shit and do not like dealing with any sort of fungus or insect infestation at all I got banner maxx, and quantum growth, greencure, a UVC light to hang in there, Also got some neem seed meal to amend into my soil mix, i hear it has a good npk value as well as immunity boosting agents. None of this PM has been found on any flowering plants yet we are only at day 23 max flowering. I think i pick this up from clone I got, all the plants I had started from seed are untouched.
