How many and what deficiencies?

[Ordonyez]

have some outdoor plants getting close to harvest. Leaves are starting to look pretty rough. What type of deficiency / deficiencies do I have in these plants?

Not really going to do anything about it now but want to learn for next years crop.

I've heard of calmag. Would this be what I am missing?

Not sure about what the deficiencies are but I circled some stuff that looks like mold or mildew on your plant.

Potassium deficiency, cold weather, and likely caterpillars eating the leaves

Turns out this plant has a pretty bad pm inssue. I did not know it was an issue and now it is pretty bad (newbie mistake). I dont want to lose this whole plant. I'm only a week away from harvest but mildew is in the buds now. I'm going to clean off what I can, spray with milk solution. I'm going to try a peroxide bath when I cut. Will this work with a bad case of pm?
