.

I see the pm in the last pic, heartbreaking.

Rather than using need oil during flower try Potasium Bicarbonate to lower the leaf PH.

Another good option is a citric acid spay to dissolve the pm and spores. I like Dr Zyme's eliminator.

,

If you have to clean up your buds at harvest try a bath in Dr Zymes (2 oz per gallon of water).

People use a number of baths, h2o2,, PB, etc. It's a good idea to give outdoor weed a bath at harvest.

here’s some better pics

thank you! this is great advice
 
First thing to do is cut off all parts infected with PM and throw it in the yard waste bin. Next thing is to stop spraying neem during flowering. H2O2 will kill spores., but use it sparingly. A 10:1 milk dilution may help, but just spray leaves.

I think you mean raise ph.
 
Also in the LA area. Congrats on your grow! Looks tasty!

It looks like most of the pm is on the lower growth. If it were me I would consider harvesting soon before it spreads to. those delicious colas. You can try spraying but at this point you likely won't kill the pm all the way.
 
thanks brotha! the terps smell so good! Second year growing i’m very excited for this harvest.

Awesome! You are a natural! Much better than my 2nd year! Next harvest you might want to consider Regalia/Southern Ag's Garden Friendly Fungicide as a preventative. My plants have been slammed with pm every year before this one. Its expensive but this year less than 20% few have minor spots of pm so its def been worth it.

Do you know if h2o2 has any affect on smell or taste?
 
Flower them all the way and then when you harvest use the jorge cervantes h202 method and wash the buds in a bucket with water and h202 and it should remove all the nasty stuff :bigjoint:

Not that I know of.

I believe that H2O2 breaks down to H2O and O. One guy on here sprayed undiluted 3% H2O2 directly on the leaves without any damage.

I spray undiluted 3% hydrogen peroxide directly on the leaves and it does kill the PM, but it isn't what I would call harmless to the plant
 
I tried a few different things but milk at 60% to 40% water did the trick. It leaves a lot of residue so has to be cleaned thoroughly. But, it seemed to be the only thing that just flat stopped it in its tracks that I tried.
I also used an H2O2 soak after harvest and there was no discernible change in flavor or smell.
