Do i spray milk mix for PM with lights on or off?

[mrubus313]

Recently found a few spots of PM in my tent. It's a small project with only 3 plants. Only 3 or 4 leaves with spots so I'm gonna try the milk spray. I just don't know if I should spray it with lights on or off? I've done much bigger grows and have always sprayed neem oil and other products with lights off but this is my first PM issue and I've never sprayed with milk. Of course I just flipped the cycle to flower 3 days ago so I want to get it under control asap. Any help would be greatly appreciated!

Milk isn’t like an oil that concentrates light and burns your plants. So not a big deal either way. In my experience milk doesn’t do squat. Since you’re not in flower why not use one of the oil based commercial products like Green Cleaner, Lost Coast, neem, etc?

I have heard milk only works for outdoor grows. Something about the sunlight reacting with the enzymes. Baking soda or hydrogen peroxide are alternatives.

Can I spray baking soda or peroxide with the lights on? I've heard mixed reviews about the milk but I figured since I caught it early that it may have a good shot of working. Just want to make sure I get some good info before I make a decision so I don't ruin the crop. But I can't wait too long lol

I'd like to try something more organic if possible but I'm at the point of either spraying with neem oil now before it starts to flower or just ride it out with milk or peroxide. Like I said I'm only 3 days into flower so technically I could still use a commercial product but would rather go the other way if possible. Just looking for as much info as possible but of course there's so many mixed reviews on EVERYTHING.

I have never had pm indoors so have only dealt with it in greenhouse. I wait until sunset and alternate between baking soda solution and hydrogen peroxide solution about every 3 days. In a tent if you can reduce humidity and increase air flow that will go a long way toward reducing pm

Wetable sulfur in veg. At 2tbs a gallon.make sure you have not sprayed any oil base product for about 2 weeks.

Any way you can share your baking soda and peroxide solutions for me? I need to spray tonight at lights off but would rather use someone's solution that has experience rather than picking from multiple suggestions on google lol Thank you for your help and response btw.

Yeah, the solution strengths on Google are all over the place. I settled on 1 Tblsp of baking soda per gallon and 1 quart of hydrogen peroxide per gallon. I alternate the 2 about every 3 days, especially when the weather is cool and wet like it is now. Works better as a preventative measure but does seem to slow it down if already present. Good Luck

1 quart of peroxide per gallon of water??

1 quart of peroxide per gallon of water??

Yeah sorry, wasn't to clear. I mix one of the quart bottles of 3% peroxide to 3 quarts of water to equal a gallon. So 1 part hydrogen peroxide to 3 parts water. I don't think the ratio matters a whole lot as some people recommend a lot more and some a lot less. Admittedly I use this ratio because it's easy to pour a bottle into the sprayer and fill it up with water but I have been happy with the results. We have had cool, rainy weather here in Virginia for the last couple of weeks. Perfect conditions for wpm but so far just a few tiny spots. Fingers crossed.

ok thank you.
