Nutrient Inputs/Sprays

ATAK Optic   Copper Sulfate, safe for  flower

Lost Coast Plant Therapy Safe for flower uses Citric Acid is organic, plant derived (from Cassava root), food grade. ACTION: Adjusts pH of plant surface. Preservative. This ingredient makes the pH of the plant inhospitable for powdery mildew and eliminates spores on contact due to its anti-fungal properties.

PM doesn’t like Silica leaves scanned with electron micrographs that had been SI sprayed showed fungal hyphae did not take hold. Also helped plant with SI applied to root zone

Don’t over use Nitrogen, because more succulent tissue is more susceptible to infection.

Sulfur  Sulfur Spray  not for flowering   

Sulphur Burner not for after day 21 flowering 

Sulfur Vaporizers (Burners) are the best overall remedy to the powdery mildew problem. It is what commercial greenhouses use for a very good reason – it works. Sulfur changes the pH on the leaf surface, making it unhospitable for plant growth. If you want the “final solution” to an infestation, than use a burner. They smell something awful (Sulfur is not safe to inhale.

Use a Digital Timer in conjunction with our Sulfur Burner and your exhaust/inline fan(s); this will manage the Sulfur application and prevent exhaust fans from turning on while the Sulfur is being applied. Hooking the burner up to a timer is critical. We also recommend having the

exhaust fan hooked up to another timer (turning on after the Sulfur burner has been turned off) to vent the room.

Application Instructions:

Perform all Vaporization of sulfur at night. 

For best results make sure to follow these instructions closely:

For preventative use turn on the unit for 4-5 hours 2 times per week.

For active infestation turn on the unit 4-5 hours 4 times per week. Can use up to 6-8 hours a night for severe infestations.

Sulfur Candle?

Bicarbonate Changes leaf surface pH PM can’t survive pH above 8. spraying your plants with bicarbonate dissolved in water might be effective against powdery mildew, but you should avoid it during flowering if you don’t want visible remains to build up.
