Should I kill it?

I have noticed a few small isolated spots of leaf damage in my 4x4, but still haven’t been able to find anything that could be the culprit. Then today I saw this thing chilling near one of my tops:
I knew it was too big to be a spider mite, and there was nothing to be found anywhere else and no webbing on the plants. It’s literally day 1 of flower, I looked it up and it says it’s. Lynx spider and then I googled that and it looks very plausible, and if that’s the case they are predatory, and he could help.
would you spray something or just let it ride?

It'd be hard to keep tabs on that small of a spider. Not sure if I'd want to risk webbing or babies later on. Tough one though. If there are pests present.. I'd let it stay a while to see what it does.
