You dont need to spray any leaves ever. Actually i notice especially the lower leaves live longer without ever letting water touch themcwhen watering. I usually lift the bottom leaves. Maybe you getting mold from too much moisture sitting on the leavesAny of my fellow growers have a good spray solution to stop white powder mildew ?
At least I believe thats what it is , First time in my yrs. has this ever happened , I mixed 2 tsp. apple cider vinegar to qt. water and fouler sprayed a few days ago ,
they looked good till tonight , I'm seeing it again , their 4 weeks into flower .
Thanks !
If you have powdery mildew you will want to spray the whole plant down.You dont need to spray any leaves ever.

Yea i guess you're right but it should never even get to that point so easy to avoid, ive even had poor ventilation and never encountered that which a fan on the upper canopy directed straight at it min 2 feetvaway and oscillating never encountered mold.If you have powdery mildew you will want to spray the whole plant down.
I don't get water on them when I water tho , got 3 fans going , plenty of air , just don't get itYou dont need to spray any leaves ever.

will do , will get a few pics after work today , but most def. not pollen . I got 5 plants 2 are cookies n cream they are on week 7 , nothing on themPlease explain how you came to a pollination conclusion without seeing a single picture, or even asking if the "white" powder is yellow (as is pollen).
@morugawelder, please post a picture or two of the issue for a proper diagnosis before you scrap the plants based on an uninformed response.

Yeah, i dont either, unless your overall humidity is always above 50 percent. Please just check for ballsI don't get water on them when I water tho , got 3 fans going , plenty of air , just don't get it
Humidity been around 40 % one day it got up to 70 because my timer tot my exhaust failed , but not for very long . The sots are white and flat no bumps at all . Kind of like dried up milk on them . But just my 3 younger girls , the 2 cookies and cream have nothing , must be more resilientYeah, i dont either, unless your overall humidity is always above 50 percent. Please just check for balls
here it is bro , I wipe it off with wet paper towels , theres more this is on 2 plants , their not covered yet but I'm sure they will be . I mixed 2 tsp. of apple cider vinegar and sprayed them down . I sprayed them a few days a go , . Gotta be a better homemade mix , they say milk and water , or peroxide ?Please explain how you came to a pollination conclusion without seeing a single picture, or even asking if the "white" powder is yellow (as is pollen).

That is most definitely not pollen. If I'm not mistaken, @Renfro has good advice for ridding a grow room of PM. Hopefully he'll see this soon to be able to respond to let us know if I'm correct that I'm thinking of the right grower, and to be able to provide some assistance.View attachment 4536070View attachment 4536072View attachment 4536074 here it is bro , I wipe it off with wet paper towels , theres more this is on 2 plants , their not covered yet but I'm sure they will be .

Once you have active PM infestation the ONLY thing I have found that will fix the problem, meaning it doesn't keep coming back, is a sulfur vaporizer.That is most definitely not pollen.

where can they be had and how does this work ? Thanks for your advice ,,,,Once you have active PM infestation the ONLY thing I have found that will fix the problem, meaning it doesn't keep coming back, is a sulfur vaporizer.
For starters, whats your grow room like, how many sqft?where can they be had and how does this work ? Thanks for your advice ,,,,
How long does it smell like sulphur after you vape it? I grow in a spare bedroom and would love to vape it but I'm worried it will make the rest of the house reek.For starters, whats your grow room like, how many sqft?

Wait at least 30 minutes after lights out for the stomata to close.
Turn off all fans, dehumidifiers and whatnot, we want still air.
Cover or remove any CO2 sensors. I would remove LED lights as well.
I wouldn't vape a room with flowering plants, it can impact the flavor of the product.
I always vape a new room before growing in it as insurance. If a room had a PM outbreak previously then a good vape will kill off the spores. I know a lot of growers that have fought PM unsuccessfully for a long time and this was the fix. After two or three treatments the problem is gone.
It's a good idea to plan on leaving the home and taking pets with you when you vape.
Some google searches will net you more information but don't let the pussies scare you off with all their fear mongering. As long as you aren't in the room huffing the vapor it's safe enough.
Yeah I figure the smell will stick in the carpet and be a pita to remove. Have you heard of heat treating? I can get the room to 115° in the summer easily for a few hours. Not sure how effective that is in killing the spores.I don't notice the smell after a day but I don't have carpet. Probably not the best for your situation.
Not at all effective.Not sure how effective that is in killing the spores.
