Problem with White powdery mildew

[superchola]

Nothing wrong with big crops as long as there 100 percent organico

But any way is a perfect reason I don't smoke industrial weed no telling what's on the buds is crazier your growing that many plants an don't know a bout powdery mildew another perfect example why I don't smoke industrial weed

My experience with big grows was awful, I transitioned from a 3 plants setup to a 100, I got spider mites and every fucking thing you can imagine XD (I still have nightmares thinking about the bugs) for me it was too much to manage but some people handle it fine I guess

it’s probably in the buds already and those buds are still at least a month away from finishing,..

PM thrives in warm DRY days and cool WET nights. It needs the swings to do it's thing. Take a small space heater and crank the nighttime temp so it's at least 5-10° hotter than when the lights are on. This will solve half the problem.

Then make a foliar spray with 1tsp per gal of armor si silica and DO NOT PH correct it, it should be like 10. Hit all the leaves with it every morning until the spreading stops.

The combination of those two should at least slow it down enough to get you to harvest if you stay on top of it.

Good luck and keep us posted!

1 to 9 peroxide soak everything should kill spores, amyloliquefaciens treatment weekly, diligence, use through bud phase my go to, run 3 day rotation if persists may also require back to back peroxide treatment

Bacillus amyloliquefaciens is a Gram-positive, rod-shaped bacterium known for its beneficial roles in agriculture and industry. It acts as a biofertilizer and biocontrol agent, promoting plant growth by improving soil nutrient availability and suppressing plant pathogens. The bacterium also produces enzymes and plant hormones, and its spores are resistant to harsh conditions, making it a valuable tool for sustainable agriculture and various industrial applications.
Agricultural Applications
Biofertilizer:
B. amyloliquefaciens enhances plant growth by increasing the availability of soil nutrients like nitrogen, phosphorus, and potassium.
Biocontrol Agent:
It protects plants from various diseases by secreting antimicrobial compounds and regulating the soil microbiome.
Plant Growth Promotion:
The bacterium produces plant hormones, such as indoleacetic acid (IAA), which stimulate root development and overall plant growth.
Improved Soil Health:
It contributes to better soil structure and can improve seed germination and rooting.
Industrial Applications
Enzyme Production:
B. amyloliquefaciens produces enzymes like amylase, which are used in various industrial processes.
Biotechnology:
It serves as a host for genetic engineering, allowing for the development of new tools for gene editing and the production of valuable compounds.
Key Characteristics
Gram-Positive: It is a type of bacteria that stains purple in the Gram stain test.
Endospore-Forming: B. amyloliquefaciens forms spores that are highly resistant to heat, cold, radiation, and desiccation, allowing it to survive in harsh environments.
Motile: The bacteria are capable of movement.
Optimal Growth: It thrives in temperatures between 30–40°C.
How it Works
Antimicrobial Secretion:
It releases lipopeptides and other antibiotics that inhibit the growth of plant pathogens.
Nutrient Solubilization:
It converts insoluble soil nutrients into forms that plants can absorb.
Hormone Production:
It produces plant growth-promoting hormones that regulate plant development.
Rhizosphere Regulation:
It influences the composition of the microbial community in the plant's root zone, creating a healthier environment for the plant.

Use Bacillus Amyloliquefaciens to Organically Control Plant ...
Bacillus amyloliquefaciens D747 is a beneficial soil bacterium used as a broad-spectrum biofungicide and bactericide in agriculture and home gardening, known for controlling various fungal and bacterial diseases. It functions by colonizing plant roots, preventing pathogens from establishing, and triggering a plant's natural immune response. Products containing strain D747 are often OMRI Listed for organic use and are available under brand names like Double Nickel, Revitalize, and Garden Friendly Fungicide.
How it Works
Root Colonization:
Strain D747 colonizes plant roots, creating a barrier that prevents harmful bacteria and fungi from taking hold.
Immune Response:
It stimulates a plant's own defense mechanisms, making the plant more resistant to pathogens.
Metabolite Production:
Bacillus amyloliquefaciens produces compounds (metabolites) that have antifungal and antibacterial properties.
Common Uses & Diseases Controlled
Vegetables, Fruits, and Nuts: Helps control diseases like powdery mildew, gray mold, leaf spots, rusts, and blights.
Ornamentals: Protects flowers, shrubs, trees, and houseplants from various fungal and bacterial infections.
Lawns and Turfgrass: Used for integrated disease management in turf.
Nematode Control: Can also be used to control plant-parasitic nematodes.
Key Characteristics
Naturally Occurring:
Strain D747 is a naturally occurring, beneficial bacterium.
OMRI Listed:
Many products containing it are listed by the Organic Materials Review Institute (OMRI), making it suitable for organic gardening.
Integrated Pest Management (IPM):
Can be used alone or in rotation with chemical fungicides as a tool for integrated disease management and to help manage fungicide resistance.
Broad Applicability:
Can be applied as a foliar spray for above-ground plant parts or as a soil drench for root protection.
