Adding milk to potassium bicarbonate spray?

Hey RIU,
I'm going to be using potassium bicarbonate to treat powdery mildew, and prevent botrytis/bud rot. Thing is too much potassium can cause a magnesium, calcium, zinc, or iron deficiency. So, since a diluted milk spray is often used to treat powdery mildew, can I add it to the spray? Would it act as a foliar feeding of these elements? Or should I alternate them maybe?
Since this year is my first outdoor grow these are new problems for me.
What do you think?

its the smell sniff again in a week lol

Neem is an easier choice so is watering less

I'm not over watering, I let them tell me when they need more. As for neem, I might get it later, for now I'll use what I already have. Still don't know what the first part is referring to...
