Powdery mildew??? Please help identify!

[CannabisseurCultivar]

Please let me know what you think about these pictures. I recently had some of my clones develop deficiencies but tool care of that. Now I noticed a white powdery substance on only one of my 12 girls so far. Please tell me what you think.

A few pics were taken under the 30x magnify glass. It seems that most of the White stuff is only on the leaves that were damaged from the deficiency.

Temps range from 68-81 Fahrenheit and humidity is high many times ranging from lowest 50 to 70

Dang. Thank you very much for your reply mongo. Yea I'm just vegging them right now. Only one out of 12 has the White stuff. Think I will quarantine it. The problem with using poison is that the grow box is I'm mu room and well, I don't want to breath in all the toxins. I also want to keep it organic, so any recommendations for organic control is appreciated!

I know you only think its on one plant bro. But its not, its all over. I see your dilemma about the poison spray. Theres some organic guys on here that say they know cures for that. Im not going to talk about then because I've never used any other then a product called green cure i think, which didn't do shit. and i sprayed it many many times on her. You have to treat everything in that room, even the whole inside of the grow space. Super good. And i guess you can't sulpher burn either.

Ok thank you bro. I may just move the box outside to spray down. I've heard of green cure. What spray do you recommend? O doing want to use eagle one for sure.

You are in for a battle my friend. I tried every organic method I could find and pm just laughed at me and continued to kill my plants with gleeful abandon. I had to go nuclear on it and used a systemic fungicide as a last ditch effort to save my crop. It's the only thing that worked unfortunately. I too wanted healthy organic buds. I am lucky to have anything left because I waited too long before I smashed it with poison. My advice is to nuke it. Sooner rather than later. I wish I had skipped the 2 weeks and numerous concoctions people suggested and just hit it as soon as I saw signs. 1/3 of my leaves were gone by the time I took action seriously. Good luck!

Did you see the post in your other thread where one said the green cure is "working" for him? Well you need something that you spray and "worked". Yes eagle is what id use if i was in your position with young clones.

Thank you skunk. The good thing, I guess , is that the girls aren't in flower yet. I may just nuke them along with the grow box and just wait till I can set them outside for the outdoor season. What nuke did you use?

 

[CannabisseurCultivar]

Ok thank you all for your reply. I'm very bummed that I just got the ladies and already having problems. A reminder of why I've done outdoor only in the past. Lol.

I will try a few things, but worst case o may just toss them all and start fresh once my grow box is finished with intake, exhaust, and a humidifier. I may have to take a $140 loss on clones but I'm glad it's happening now as clones than if I was already blooming.

Thanks again skunk, mongo, and everyone else who took the time to reply and help out! God bless brothers.

This is what I used. Same active ingredient (myclobutanil) as eagle 20ew. I'm in NZ so don't think we have eagle down here. This did the trick though. I don't think its as nasty as eagle as it has less ingredients. It worked instantly and the plants responded well. No sign of it since and that was a fortnight ago.

One more question, what could I use to disinfect, sterilize and kill 100% the mildew in my grow box? It's made of 1/2" plywood.

Did you buy those in california?

 

[skunkpunknz]

Not a hundred percent on that one but I would probably use some H202 in a spray bottle and give it a good drenching.

Yes I did. At a club in Oakland.

Those motherfuckers.... Did it to me last year as well.

Dang serious? Not cool. But like I said earlier, seems that only one has it now, but I'm sure it will spread to the others soon enough if i dont take action. But the one that has it is from a different clone company that I usually don't go with but they had the stain I've been wanting for some time. Well they claimed it was that strain.

Is that hydrogen peroxide? I know I said I don't want to use harsh chems, but do you think eagle would work to drench the grow box?
