Powdery Mildew and How do i cure it?

Fellow growers upon inspection of my fabrics pots.I noticed on the side white mildew looking substance.I started looking up remedies and decided to try a backing soda mix for a flush to rid the mildew from the soil.I am 8 weeks into flowering almost done so i wanted to know will the baking soda take care of the mildew? Or should i do a flush with neem oil to attack the mildew?

Picture? Are you sure it’s mildew and not salt build up from nutrients?

If it’s wpm then hydrogen peroxide and water spray it


I’m with @Nicky I think you are looking at some salt or mineral buildup, and again with Nicky on the peroxide water mix. I use the peroxide mix on a regular basis probably every third week I spray down my tent plants and all until they start to flower then I avoid them with the spray, but I’ll hit the floor pots walls etc it oxidizes any mold spores, bugs don’t like it, and it gives your plants a boost of oxygen


Yep, another vote for salt/mineral deposits. You will know by its appearance, salt will look like a tide mark around the pot

I don’t see anything on the fabric of the pot. If it’s on top of the soil it’s normal just mix it in be it white or green it’s common.

I don’t have a picture to show you the green moss that grows on the top of my coco but it happens.
