how bad is powder mildew?

[little-soldier]

Got that crap on my crop but wanted to know if I can just control my humidity or if i really have to kill it and with what and how hard is it to get rid of?
I remember having spyder mites before and safer's end didnt even seem to bother them so I didnt bother, I trashed these bitches

Powder Mildew sucks brother. You need to kill it, just adjusting humidity levels is not going to cut it. Go buy or order some Oraganicide and all(or most) or your pest, mold/mildew problems will be gone. Just follow the directions on the back of the bottle. Smells absolutely wonderful too!!!

SMC leaf wash is another product that will put a hurtin on some PM. Smells wonderful too if ya like coriander. Mmm.

Hey Little-Soldier,
I hear it is pretty bad to have that white powdery mildew on your plants. If they survive, you can get sick smoking the weed. I've heard that burning sulphur for a few hours a day, while the lights are off will get rid of it. Let us know the route you go and how well it works out for you.
Peace,

Im planning on using nutrilife SM90 but it says not to mix with organic and im doing hydro with floranova and floralicious plus. floralicious says its organic on the bottle so does that mean not to use sm90 with it?

Depending how far along you are you may want to use something like Serenade and skip the sulphur burner....I know some floks that don't use sulphur at all once flowering begins. Spot spray if you can and get the humidity down to 50% ASAP.

Powdery Mildew is a bitch, if left untreated will destroy your harvest. I had the pm for what seemed like forever. I tried everything, Dehumidifiers, Sm90, Organocide, I even bought some shit they use on golf courses. Until I came around this thread about pm Rx here is a link http://www.icmag.com/ic/showthread.php?t=43220&highlight=powdery+mildew
post 15 and beyond. Mark699331, has the remedy. Just dutch master's zone and penetrator, and you see a big difference right away with his remedy I shit you not.

This is the most important question right now, how far into flowering are you?
Depending on how far you are in, you will have a much harder time treating it.

I have a theory that supports why Penetrator and zone work so well.....To find out for yourself check the ph of that mix the next time any of you make up a batch. It is almost always between 10 and 12......

My theory is this adn it seems to have done the trick with my girls... Ph water of 11 using earth juice PH up, with a few drops of liqiud soap detergent. the detergent acts as a wetting agent for foliar spraying much like penetrator does and the PH of 11 fazes out the mildew the PM has no chance on an alkaline surface....To prevent any burning I foliar Ro water after a day or so to rinse off foliage...As this contains no chemicals I assume it can be used even in flower....Although your environment has to support the evaporation of liquid on the surfaces of leaf tissue fairly easily as to much water in the bud could cause an even worse enemy bud rot......

This method worked like a charm for me and did what serengade could not....
