Ok so first off hello to the fellow community I use too have a thread here as a kid back in the day like a decade ago but times have changed. I M an all organic no till gardener and I am having issues with pm right now......

I have tried serenade and it has kept it at bay but will not dissolve it...

Now I hear Isopropyl alcohol or hydrogen peroxide will do the trick....

Is this true if so which one how much to the gallon what kind of sprayer and lights on and off please help me out I could really use it..... by the way I have some things I can harvest now so I will just tough it out but the stuff that has a couple weeks I need to treat so I am mid flower....

only use a tablespoon or so per liter of that kind of stuff. i like EMe, kombucha, neem oil, fpe, those kinds of things. iso isnt really an organic in my book

Everything that is below 2 weeks in flower is getting full head to toe makeovers, I'm talking individual inspections and cutting anything out we have also increased our air flow, restricted our water and added more dehums..... i need a solution that will take care of it ya know I'm tired of just spraying shit on it n hoping it will work

what kind of lights are you using?
I've found that the 10k metal halide bulb with all that UV tends to have PM free grows.
I did a whole harvest last yr during the huge CA rainstorms and I didn't have a speck of pm. It rained the entire ending of my harvest

1 tspn of baking soda per gallon, a few drops of vegetable oil, a few drops of dish soap. Only problem with it is if the PM is bad you'll have to spray every 2 weeks or so. once the buds are set spray in the dark or turn off your lights and run a shop light until they're dry, otherwise it can burn the hairs.

It's more effective, I tried milk and it worked but really short term. if you spray this in veg before they go in, you're less likely to get it. I have to use it outdoor most years, this last summer was freakishly hot and first year I didn't have to spray.

I'm in week 3 of flower and milk has been working but I have to do it everyweek. you think if I do ur mix I can wipe it out with a few applications. I'm not very comfortable spraying ANYTHING being this far along. The milk hasn't hurt anything and I can spray it wit lights on(at least that's what I was told and I haven't seen the plants hurting at all).

If it's working and you don't mind re-applying it weekly that should get you through the round. If it's in your area you're likely to get it again as it's too easy to bring it into your garden short of changing clothes and showering every time you go into your gardens. Try applying that baking soda spray in veg as a preventative.

Forgive my ignorance but how does milk not make the bud get funky smelling? I've heard of this method plenty but have never tried it. Just neem oil and baking soda.

It kind of does, another reason I didn't like that method. I have a sensitive sense of smell and it kind of smelled sour to me.

UVC lights will kill it. It's not a great way to deal with it if it's gotten out of control but it will actually kill it and control it effectively. Takes quite a bit of time to run through a large garden though.
