Strange splotchiness has recently showed up in a few of my plants in different parts of the garden. I was thinking maybe CalMag deficiency? But I wanted to get an expert opinion. See latest photos.

Hey Kegman, as you're outside you're going to get a fair bit of issues with pests, check the bottom of your leaves to see if you find absolutely microscopic pests, like small black dots or otherwise... look for signs of aphids too just in case, i dont think it's that but it pays to be paranoid so deep into veg.Anyway there are a few ways to get rid of them, including commercial and toxic pesticides, but long term you do want to go bio, perhaps by adding beneficial bacteria in your watering and as a spray. dilute 15g of Bacillus Subtilis, bacillus thuringiensis, bacillus thuringiensis israelensis and mycorrhizals, spray every three days at night for three weeks, add it to the water every 10 days and after three weeks stop the spray, it will control the outbreak, so that the bugs wont reproduce. Hope this helps ! :rocket::

Yeah it looks like calcium mainly, and possibly some magnesium deficiency. Pests could affect that, other nutrients/minerals could affect that.
