Hi Smokes! Yep, Glen and his Dr buddy have a lot to say about brix and how it relates to things like that and also things like molds and such. Powdery Mildew comes to mind for us. He's all organic, I don't know how to transfer that to other feeding ways but I'm thinking it can.
This one stood out because PM is something that can hit all of us and he says if you can get brix to, oh crap, 10 I think then PM won't be able to take hold. I'm just starting this so I can't say much but so far no PM and no major bug issues this year for me. The only other thing I'm using is Bauviera bassiana sp. spores.
@InTheShed I'm thinking of you and the PM battle, but I don't know how to get it done with your feed regimen if you were interested.
