Will this process be fine in flower?

It is now August 6th and my plants are beginning to show their sexes and some are starting to bloom. This is a legal, outdoor Colorado grow with good airflow and generally low relative humidity. I need to take care of this powdery mildew problem before it gets out of hand. I was using an organic fungicide known as organicide until more recently. It was very oily and smells like fish scales. The organicide doesn't seem to work very well in my opinion tho. Does anyone have an organic product they could reference me to, preferably not a home remedy. Remember there are buds and buds ones on my plants right now. Thank you for any help!

id wash the leaves really good with dish soap and water, then spray some water and baking soda at 1 tsp to a gallon every night for about three or four days...good luck

By wash do u mean heavily spray with one gallon sprayer or like hands and knees with a soapy dish wrag type wash? Lol

Just be sure to rinse the soap off, the ligth will burn the leaves if they are covered in soup in the morning

good to know! haha and thats relief i wasn't looking forward to hand washing leaves!!!

I do azamax neem combo but more with just neem as it's supposed to control PM Azamax is just an anti feedent for bugs Remember with neem a lil soap help mix it up I use a couple drops of dawn in my spray bottles

Ive never had nor heard of burning caused from soap? I spray at 1 tbsp per Gallon of water and let the rain rinse it off during vegg and they've always been fine

Bro take your pic down. Georgia ain't Colorado.

I use H2O2: 2-4 tbs to 1 gallon of H2O and drench entire plant, especially spots.
The extra O burns the cell walls of the fungus.

Manganese and copper foliar will help a lot. If your copper and manganese are high enough, you can't get PW. The more your soil is balanced the less problems you will have. If you are in GA, you are probably sitting in a lot of iron, which is the enemy (antagonistic) to manganese.

Calcium oxide applied to a pH of 11 or so also works well.

green cure potassium bicarbonate.... @, I use serenade on my outdoor garden, stuff smells like death tho.
