Spider mite damage, but few mites

Hey all, I'm about a week or 10 days from harvest of my lone outdoor plant. I noticed a red spider mite problem back in the heat of summer (July) but it pretty much went away after a week or two. I think the predator insects pretty much destroyed them and they never really got a foot hold! I haven't seen any other mites since then. I've seen occasional mite damaged leave but they were so few I didn't worry about it.
Last night when checking my plant I noticed quite a few mite-damaged leaves. See attached pic. However, I couldn't see any active mites anywhere on the plant. No webs or anything like that. I think I did see a few eggs on the underside of one damaged leaf. Temps right now are high 70s during the day and high 40s at night. Hopefully any mites will die off in the cold weather! Humidity also ranges from 15%-70% throughout the day.
Do you think these mites will affect the buds at all? Do mites even mess around with the buds? Since I didn't even see any mites I assume it's not going to be an issue. And I doubt they can get a foothold with the weather being what it is.

What do you think?

Also I think the leaf damage was caused by a different species than the red spider mite. Those things seem pretty harmless outdoors. They were huge and easy to see and they just seemed to run back and forth on a leaf all day seemingly not causing much damage. I assume the mites that caused this damage are much smaller considering I couldn't even find one!

We get two-spotted spider mites here...the damage looks the same. They are pretty small. Kill them before you see webs.

"Tetranychus urticae is extremely small, barely visible with the naked eye as reddish or greenish spots on leaves and stems; the adult females measure about 0.4 mm long."

Do you think the cold weather will hold them at bay at this point? As long as they can't get a foothold and start increasing population I'll just let them be. There's plenty of predator insects around as well. I don't want to spray anything at this point. If they start getting a foothold I'll likely just harvest early before they can taint the buds!

I wouldn't give it a second thought, so close to harvest, who cares. You will be fine. If anything mechanically remove the most infected areas.

Vibes!
