Best thing I’ve ever seen for white powdery mildew

Over the years I’ve tried everything I could think of - different brands of neem oil , ipm , several other products . Even peroxide and water - they’re all work to some degree but take awhile to get rid of it , if it’s bad .
I had a small plant in the back corner of my tent , that had been neglected for a week due to my kids bringing home the flu . I got in there yesterday to check on it , and it had WPM all across the he top of the plant on leaves stems and flower ,

2 minutes before lights out - I mixed up water and lost coast plant therapy - shut my fans down , sprayed the plant down heavily , expecting to re apply every few days . This wasn’t the case , I got up at 6am this morning and there wasn’t even a single speck of the powdery mildew anywhere . This stuff literally ate/killed every single bit of it , and left no smell afterwards . It was minty when I sprayed , but the smell was completely gone , I think I found a winner for fighting it - the only downfall is it is prettt pricey - 12 oz bottle retail locally is 29.99 , I’m sure you can find it cheaper online -

I really wish I had taken before and after photos but never expected it to work like that

picture is for shits and giggles . An early tester bud from a different plant that doesn’t seem to be affected by wpm at all .

Its not safe to use in flower unless you dont mind smoking soybean-corn oil, Citric acid much safer an cleaner when in flower.

If that is the case , and there’s some scientific fact to those ingredients being harmful , then Somebody should file a lawsuit , considering they claim it’s an all natural insecticide and 100% safe to spray up until the day of harvest for cannabis .

Citric acid is one of the main ingredients in it . Now I wouldn’t trust it up until the day of harvest , but I would have no problem spraying them 2 weeks before . I’m curious where would I send a sample to , to test to see if anything residual and harmful are in the flower ?

Oil stays on your plants for a long time. Its not poison, it's soybean oil. So it will likely affect the taste. Lost coast is good if you've got money burning a hole in your pocket. You could just use citric acid which is the main ingredient as well as some peppermint extract (secondary ingredient). Prob cost about 15 bucks to make gallons of the stuff. But hey if you got it spend it I guess.
We've all been using citric acid for years for bugs and mold. it's not a new miracle spray. The oil is used to keep it on the plant but you can use many diff surfactants to achieve the same goal that aren't oil based.
Here's the other problem. There is little to no regulation on products for the cannabis industry. It's like the wild wild West. They can claim it's safe to use until harvest because there's prob no tests to confirm soybean oil is harmful to smoke because the tests have never been done. So ya it's safe because nobody has made a claim otherwise because it's never been tested. And define 'safe to use'. Does that mean it's safe for you to consume? Or is it safe because it won't harm the plants... I duno. Do you? Big companies trick people with buzzwords like 'natural ingredients'. Ricin is natural it's found in castor beans. Snake venom is natural, mercury is natural..... Doesn't mean it's safe to consume.
Dont fall for industry buzzwords. Do research yourself instead of trusting someone who wants to take your money. Like charging 100$ for 500ml of water mixed with oil, peppermint extract and citric acid.
