Powdery Mildew in Bloom

[Dan789]

Hey everyone it's been a while since last I posted anything here. Suffice to say with things at home I've been busy with a sick wife. So on this grow, I got lazy and ended up with some powdery mildew on my plants. I'll post some of the bud shots on two plants I chopped a bit early @55 days. I hope these shots are good enough they're off my computer screen so bear with me.... Any helpful comments appreciated.

Glad to see ya again, and sorry to hear about your wife being sick and the PM. Not much you can do at this stage except hold on for the ride.

Thanks @Hippie420. Can anyone confirm the lacy white I’m seeing in the buds is powdery mildew…..

 

[Hippie420]

Any PM I've ever seen wasn't lacey. Looked like a fine dust.

 

[Dan789]

Looking at #91 & #92 the white lace like structure appears when you enlarge the shots……

I must be blind. I don't see the PM.

Is it anywhere else on the leaves that are not just buds?
I see what you are talking about and I am on fence about it.
Did you do weekly sprays to prevent or even Biweekly ones?

Can you post a picture of the affected area that is not zoomed in?

 

[Dan789]

Here it is…… that’s not sugar….

PS I’ve ordered the ZeroTol 2.0 so just waiting on its arrival. I’ve got other indications on some leaves also….. Anyway I hope i can salvage some of this…..

If its pm cut the affected buds off to save the rest

 

[Dan789]

Yes I’m cutting off anything I see as affected…..

It looks like PM to me. Only thing you can do depends on how far into flower you are, which it looks like you're pretty advanced. Cut off all affected material. I spray in flower in like week 3 or 4, Tiny buds, really doesn't affect anything.Truly, the only way to totally get rid of it is getting rid of all infected plants, then Clean the growroom with weak bleach solutions(everything).Even then you may see it again. PM and mites are 2 things you have to be vigilant about not letting into your garden because once they are there, They will stay for a while.

You could hit it daily with monopotassium phosphate. it helps a lot and is claimed that it can be used till harvest

Hydrogen peroxide works really well for cleaning a grow room, too.

True, I didn't think of H2o2. Gotta get the nuclear strength stuff.

 

[zem]

for the room you can use simple bleach. For the plants, be very careful with h2o2 IME. i got golden leaves within an hour once. you could wash your harvest with dilute h2o2 too. look up cervantes bud wash technique on youtube.

The nuke strength stuff will frost your corneas in a heart beat. Eyeball protection is a must. I've got some 35% stuff that I cut down with distilled water.
