unfortunately I have been having recurring issues with PM slowly showing up in small patches on my plants. I am 5 days from planned harvest date and just giving the last flush before I chop, I noticed some small PM spots on a few buds. Can I spray the plant with a baking soda solution to kill the PM, or will this negatively affect the flavor\smoke of the final product? If I do spray, how long should it be before I chop?
