Will having a high brix prevent a plant that has PM in its system from showing spots? I've read that grapes once they are 12-15% mold/mildew no longer shows up and am curious if it's the same for Cannabis. But I did read it on the internet so who knows if that's even true.
I don't have PM right now but I've had in the past and was just curious about that.
Acidic soil attracts insects, while alkaline soil attracts molds, rusts, fungus, etc. Higher Brix=resistance to disease and pests, including PM.
I don't have any issues with PM at all. Like I said above, I do have mites and thripes for sure. I ignore them, mostly. Every now and then, especially when it's just days before harvest and the plant is slowing down, I'll see some webbing. It all gets washed off.
I have no fear at all over insects in my garden. Some growers I know haven't had any sign of mites since going High Brix.
