Yellow spots on oregano plant

Oregano   

Hello! I've been having some problems with my garden, I'm kinda new in all this, one of the problems I have is this yellow spots on my oregano plant, I think they've been there since I plant it, anyway, anyone can tell me what this spots are, and how can I help my plant? Also recently this spots appeared on my green bean plant and I'm really concern about it! My oregano plant also has some recently weird thing on some leaves, I'll attach the photos I took. Thank you so much!

(Sorry for the bad quality image!)

Are these plants growing indoors or outside, Romina? In containers or right in the ground? In natural soil or soil you've mixed for raised beds or containers?

Hi! the plants are growing outside, the oregano is right in the ground, the green bean plant and the cherry tomato plant are growing on old car tires. I used soil I bought from the nursery, I don't know but I suppose it's natural soil, in the package it says 'Super Soil, certificate category 1'. Thank you!

looks like mite damage from the photos, any sign of webs?

Yes! actually today I found a web very near the bean plant, but I don't think it was a spider mite's web even though there was a red spider! something like this ones:

In the oregano plant which is the one with more damage I haven't found any web. Thank you!

The photos are a little blurred, so it is hard to see clearly, but I am wondering if it might be insect feeding, particularly thrips.

Romina commented,
yes, I've been reading a little about that and I believe that's the problem too, do you have any idea what can I do to control them? thanks for your answer, and I'm sorry for the blurred photos, I'll try to take better ones.

There are many kinds of thrips, but all damage leaves by their rasping feeding which scrapes away the leaf surface. I would suggest trying some non-chemical options at first. If the plants are outside a good rain does wonders. Along that line, I have knocked down mild infestations with a water spray. I have personally not had much success with insecticidal soaps, but other people find them useful. For sprays, pyrethrins or neem work pretty well. Many people recommend predatory insects such as pirate bugs, lacewings and lady beetles - I have no experience.
