is there powdery mildew on my sour diesel?

[stonedstoner]

so this girl is in 7th week of flowering (day 45). i see some white spots on the leaves that don't look like crystals, but there aren't very many. this plant did have some powdery mildew in veg that i eradicated with a sulfer burner. now the humidity has been up in the high 50's and low 60's, and sometimes even goes up to 83 percent during the dark cycle. so that's why i fear that the pm might be coming back. here are some pictures...tell me what you think..thanks...

they are just tiny little white specks on the fan leaves...but they are spread out...not bunched up or anything...can you see them?

It's hard to see anything in these pictures, but the last picture tiny yellowish dots look suspect of what might be the borg just getting started.
Take a very close look at the bottoms of those leaves in that last picture for the tiny bastages !

Now about that heavy trichome production, wow...or is it. Anything feeling soft most and gushy gooey and grey in the buds ?

I don't see any PM. Try and get a close up of the exact spots your talking about.

Even if you have PM.......there is not much you can do this late in flower. I would suggest spraying with plain HIGH PH water. Like 9.0. Spray approx 2 hours before lights come on and let fans blow most of it dry before lights come on. This will wash away 99% of the PM on the buds and leaves. Good enough to get you to harvest.

Yes your humidity is way to high at night. Your gonna end up with Bud Rot as you get closer to harvest. However.......keeping your humidity low will help but not prevent PM from coming as some say. I've run my RH at 30% with air temperatures at 80*F in a sealed room and still got PM.


Hope that helps !!

ya i think i see the pm. its not too bad, how many more weeks you got to go? i would leave it for a bit if its ok and not contaminating the next batch, or something like that.

Long time no see... oil man !

83% rh at night is just asking for budrot...
Keep the airflow and exhaust going all night or you'll be very sorry stonedstoner

 

[stonedstoner]

but what do i do? i don't think my outlets can handle a dehumidifier on it, with the hps, fans, and a/c already taxing the shit out of them. what can i do to make sure i don't get any pm?

the sour diesel i think is supposed to go for 70 days, the white widows go for 70, and the jack the ripper goes for 63.

You were concerned about those tiny specs on the leaves, visible in the last photo...
Did you bother to LOOK at the bottoms of THOSE LEAVES with the tiny specs or not ?
Picture isn't conclusive in any way but you DID mention the specs on the leaves, and such specs could be (mite be) cause for concern.
I feel like that just went right over your head arrrgh !

You also mentioned the super high night time humidity running as high as 83%. sheeesh !!!

So I said...

And you then said...

Ahh... well as I stated you should "TURN ON THE EXHAUST VENTILATION and keep the air moving FULL TIME", especially during the night time periods when the plants are transpiring their maximum moisture !!!

Sorry, I wish I didn't need to yell (caps lock)

i don't think i have mites dude...no one else has even mentioned that after looking at those pics and i haven't seen any, so you know probably no mites. you were also wrong about the jack being seeded, it's not. no seeds at all.

Yo Bra, your outlets "hps, fans and ac" are "only" on during Day hours so when your humidity is up you could use a dehumidifier at Nite, as it and some fans would be all thats on your circuit.

Hey, you asked about the specs and I told you what such specs are very often an early indication of. If you looked at the bottoms of the leaves you said had specs on and didn't see any then that's just great. btw..noone else needed to mention it since I already did tell you what such specs could or might be. I also asked you to look, did you.

Imnsho, the jury is still out on whether or not you'll find any seeds in there since you have yet to harvest and begin curing cleaning and smoking, I and others did see a couple very fat calyxes on a couple of your preflowers below your fine buds that are starting to split open, regular fat calyxes don't just 'split open' like that without having a bean in them.

But all that is beside the point in this thread. You can choose to ignore advice about getting that high humidity (83% over night) out of the growspace, especially full time at night if you wish....but you're risking a serious case of bud rot if you blow off that advice too.
