I did as you said! I have hope the rest of the season now. Thanks!Potassium Bicarbonate 5 tbls to gallon of water with some surfactant as a foliar feed is said to work.
Potassium Bicarbonate has a pH of 8 and can damage the soil. So be careful.I did as you said! I have hope the rest of the season now. Thanks!
I hope so too. Another thread they are talking about copper sulfate. It would be lowering the pH but copper sulfate is a killer for roots.I did as you said! I have hope the rest of the season now. Thanks!
Hi there HammerIf you don't have a stable environment that keeps temps, and humidity stable you will need to use IPM to keep PM out of your garden. It's not difficult to do.. There are many organic options that work well. You have to do this regularly. Keeping your indoor room at 78f with the lights on/off and with a 50% RH you will not see PM.
Outdoor is even easier using the same method. You might need to do it more often depending on weather conditions.,
Powdery Mildew grows when the temps and humidity change a lot between the day and night. The fewer these change the better. You should try to keep temps swings less than 10deg. Humidity has less of an effect but still try to keep it between 50-60 % during flowering. You could go lower 40-50%.. Plants like more humidity.
Nutra fog, adds nutrients...
Resistant plants are more efficient at extracting nutrients...
Well fed in veg (right balance of nutrients)...
One key is balanced nutrition. Balanced nutrition is significantly easier in living soils.
John Kempf points to the curcubit crop they planted in rows across dead soil and living soil. The living soil plants had no PM issues, even when their runners were growing across PM infected plants in the dead soil. Same plants, different nutrient absorptions, different health.
I see you've applied a remedy but if you're outdoors Builders Lime (also called slaked, hydrated) can be used in two ways. Half tablespoon per gallon as a foliar ... and a light sprinkling of lime over the soil surface helps keep fungus/mould away.Almost the end of the growing season, and half my crop has white powdered mildew. It’s been a long season and I want to roll into a ball with ice cream and cry. Is this fixable? I didn’t add pictures because no one needs nightmares tonight.
