Using Lactic acid bacteria to treat powdery mildew in flower

Just checking to see if anyone has any experience with using labs as a soil and foliar treatment for pm in flower.
I’ve read reports where it was fairly affective for control and prevention.

It would lower the leaf/bud ph, that would help with the PM. Food safe.

So I can use labs as a foliar late in flower?
