I need help please. I have been growing for almost 8 years. Never had a problem until now. Please if you can identify this and help with any solutions, would be greatly appreciated.
Temp between 70 -75
Humidity @ 40-45
Fans going and I find this… please tell me it isn’t what I think…mold…!?!
Any ideas on how to rid before it gets out of hand? Any help appreciated!

Looks like powdery mildew, they have a bunch of all-natural sprays for that. Segregate the plant if possible because it can spread and get some spray and make sure it doesn’t come back. A filter check might be necessary

Are you indoor or outdoors, and how many plants stuffed in a tent if indoor …

Powdery mildew. You will need to get your hands on dusting sulphur ( cheap as chips ) to remedy the plant. Definitely get that plant away from others, and be careful it does spread very quickly. So dont touch your other plants with dirty hands.

Indoor right now.
9 plants in a 12×13 room. No tent.
Can this be fixed? So I don’t lose it all?
Have y’all had success?
Just turned to flower 1 week ago.

Do you all nine plants look that way or is just one
Found on 2 after closely inspecting.
Used a peroxide-baking soda-Dawn, spray diluted.
Then today went to a product called"Green Clean" all organic. Also, clipped off much of the lower and center foliage. New room filter.
Fingers crossed 
I get ahold of this!
Thank you!

Little afraid to use sulfer on an inside grow.
I don’t know much about it, other than you shouldn’t breathe it.

Here’s what I used! My pm got really bad and it’s now under control after 2 applications! Works wonders and can be used all throughout the veg/ flower cycle!

That product is oil-based and will not be ideal as fungicide , the fungicide mode of action for oil based products its more preventing and isolating the spores , but not killing .
Preventing by forming a oily layer on the surface so PM cant be in touch with the surface , or by isolating the spores with oily layer , so they cant spread . Both things will not last more then a day , because the oil will degrade quickly . You will need something to kill PM .
ZeroTol 2.0 is a combination of Hydrogen Peroxide and Peroxyacetic Acid will kill surface spores or GreenCure - potassium bicarbonate will work too .
You will need two applications , first to kill . And second with higher pressure to wash the dead PM from the leaves surface . Many people after the first application think that the product is not working because the white thing is still there , you will need to wash it . They are easily washed from surface once the PM is dead .

Do you do more than just 2 applications?
At a more diluted the solution?

Just browsing topics after writing a detailed technical document for a client about the cannabinoid CBG. Did you know its being potentailly used as a fungicide and insecticide. Just putting it out here as I found it interesting. CBG the mother of all cannabinoids.

Really???
Any added info?
How to use?
Amounts?
Where to get CBG?
CBG is a fairly new cannabinoid on the scene, and a minority cannabinoid on the spectrum. Seems like TGA Subcool had developed some strains with high profiles of CBG, and you can get a few extracts. The one article that mentioned it being tested as a fungicide etc is here. Hope that helps.
