I think you have a combination of problems going on here. I think your most pressing problem is whatever is causing that funky discolored growth. I've grown outside for a few years now and while I do see purpling when the temps drop, it is absolutely not in that pattern you're showing us.
I think you have either broads or russets, and some nutrient issues that are otherwise very slight, at worst a Ca- that can probably be easily remedied since it's fairly early on before full flower set.
60x won't show you these pests, you're going to need a much higher magnification. After the 2nd set of pix, I'm leaning more towards pathogen or broad mites, and to be clear, NEITHER of which I've experienced to this point.
