Please HELP!! First time grower

Hi,

I started growing some plants this year and decided I would switch from outdoor to indoor. Everything was going fine until I got that powdery mildew stuff. I am 5 weeks into Bud now and I cant seem to keep it at bay. I have tried to insecticidal soap from the local hydro store, (did not work) and the dawn dish soap, canolla oil, baking soda and water which seemed to work. Now that I am so far into bud what can I do? My Temp is good my humidy is only 40, I am watering with plenty of time for it to dry and I am bottom feeding. I dont want to lose my first crop. Help!!!

Spray on plants every one to two weeks. Potassium bicarbonate– Similar to baking soda, this has the unique advantage of actually eliminating powdery mildew once it's there. Potassium bicarbonate is a contact fungicide which kills the powdery mildew spores quickly. In addition, it's approved for use in organic growing.

8 Organic Treatments to Get Rid of Powdery Mildew

1. Potassium bicarbonate
2. Milk
3. Neem oil
4. Vingar
5. Baking soda
6. Garlic
7. Sulfer
8. Copper fungicides

1. Potassium Bicarbonate
Potassium bicarbonate is a safe, effective fungicide that kills spores on contact. Like baking soda, it is also a great preventative treatment because it raises the pH level above 8.3—an alkaline environment that is not ideal for fungal growth.

How to Use:

Mix 3 tbsp. of potassium bicarbonate, 3 tbsp. vegetable oil, and 1/2 tsp. soap into a gallon of water. Spray onto affected plants.

2. Milk
Numerous studies have shown milk and/or whey to be even more effective at killing powdery mildew than chemical fungicides. In a 2009 study by the University of Connecticut, which tested a milk treatment of 40% milk and 60% water on plants infected with powdery mildew, "the milk treatment provided significantly less disease than the untreated control, and the chemical treatment had equal or significantly less disease than the milk." Scientists are not sure why milk is so effective, but they believe that when milk interacts with the sun, it produces free radicals that are toxic to the fungus.

2 Ways to Use:

• Mix 60 parts water with 40 parts milk or whey, and spray onto the affected plants bi-weekly. You can even use whole milk without dilution for a strong effect.
• Mix 1 oz. powdered milk to 2 liters of water, and spray onto affected plants bi-weekly.

Hope this helps best of luck.

BTW after you crop is done you should use a sulfur burner to kill any spores in your grow room.

Is your temp dipping hard at night, your humidity has to be higher than 40 low humidity and fluctuating temperatures is a no no

My temp is regulated and stays between 75-85 max humidity is between 45 and 55 I didn't mean to put 40. I have a system that controls the Ac, dehum and humidifier when and if needed as well as heater which isnt relevant this time of year

Is it ok to spray this late into bud?

My plants are not touching each other either so I dont think it is a crowding issue. I have worked so fricking hard on this crop lol it cant be a wash!

Spraying with insecticide will not help a mildew problem , you need to tackle the base of t problem before anything

Do you have fans in your grow area

You need exhaust and circulation or you’ll get Mold and mildew

I don't know what that problem is. I believe the clones I bought had the PM on them when they arrived and I have been battling this since day 1. (Never buying clones again). I just dont know how to keep it at bay for thr next few weeks before I can trim. I am stressing hard about this.

Yes I have 6 lower fans and 4 large fans over top of them. I have it exhausted through a charcoal filter for air in and out. I also have the dehum vented out through a filter to keep the heat out.

The reason I believe it came with the clones is because everyone I know, including the guy who cut the clones has PM :/ really trying to find a source here, but everyone who I have talked too, and the few people I have shown my room too all say there is no reason I should have PM. So, I am not sure what to do at this point. I just dont want to lose everything
