Hey there my friend, these things happen when you grow outdoors right ? Like bugs jump around and sometimes they visit your plant. It becomes a problem if they decide to make a home on your plant though. Looks like it could be any kind of bugs, so the good news is you don't have a fungal infection! Check the leafs very carefully to see if you can find them, like Dilli said check the underside of the leafs for really microscopic black spots. Those are spidermites and they are the worst! Others are still bad though! To get rid of them my prefered method is biological : look for beneficial bacteria like bacillus thuringiensis Israelis - also called BTi - this bacteria is very powerful and it will attack and control most pests, eggs and larvae. Hope this helps ! 🚀
