Powdery mildew just had it itās a pain in the ass
You should do a thorough cleaning and check every leaf pull and directly bag em without waving them around or youl have more spores in the air disinfect what you can and GET A FOLIAR FUNGICIDE SPRAY how badly are they infected? Once you get all off spray with 1/2 hydrogen peroxide and 1/2 water to keep it at bay once every few days until you can get a decent fungicide nutrol , trifecta, serenade humbolts flower shield are a few that work
Humidity swings were my issue
KC, may suggest you check out the thread ārevisiting VPDā¦ā check out the chart for different growth stages. If you stay within the parameters you are going to greatly limit your exposure to PDā¦hope it helps!
Right thanx for the info. I completely ridded every leaf that was affected. I used baking powder 2 table spoons to a gallon. Rained today but no signs as of now. O I did wipe all main stock by hand on lower base of plant.
Arrrrgggghhhhā¦lolā¦ this is why I love outdoorā¦ I can blame this shit on environmentā¦ indoors you have total control to a degree so it falls in ones lapā¦lolā¦
Did u use baking soda or powder? I use baking soda and horticultural soap for my outdoor girlies for a preventative
I used baking soda that was a typo

Check out our āMildew Cureā product. Itās available and registered in most all states. It has been used by growers for many years in keeping PM under control. In most hydro stores and online in pints to gallon sizes.
OxineĀ® WT (CLo2) used in your irrigation water will eliminate this problem from the source, your soil/growing media.
Another way to fight this issue is if you are using any type of wet wall type humidification systemā¦ you can add OxineĀ® WT to your reservoir water.
Pathogen control can be achieved at a very low dose of .5 - 2 ppm. At this low level we have not had any issues with our product neutralizing any nutrient mixes that our customers have been adding to their irrigation water.
take a look at our website.
OxineĀ® WT is OMRI certified organic and EPA approved for use in irrigation watering systems as well as a surface disinfectant. Compared to other products it is the most cost effective pathogen control product on the market.
As a surface disinfectant, it is 10 - 20 times for cost effective compared to other Clo2 products.
