Noticed web on 2 plants

hey all well last night i was all hammered up so anyways went and did a close look at a few plants and sure enough noticed a little web under a leaf only 2 plants i noticed had these so i isolated them.
Being im in 3rd week can i just go with 1 to 3 strength of rubbin alcohol and water mix and spray the plant. i bin readin lots of ideas i just need to know what will get rid of them and not harm plant , can i over spray plant with raid ??? like i said the plants were cloned sept 6 and i am jus goin into 3rd week of growth.
There in potted soil . thank you all for your help

PS: WHERE THE HELL DID THEY COME FROM TO BEGIN WITH ???
PLANTS ARE LITTERALLY IN A OPERATING TBLE ROOM LOL

I would hit them all with neem or some sort of plant insect killer every other day just to be safe. If spider mites and they get a foothold, they are a bitch.
How did they get in? Probably on you. Unless you go through a decontamination procedure (shower, wash hair, and change clothes before entering) a lot of things can hitch a ride on you.
Also any plant, clone, cutting, soil...Any of those brought into a clean room can bring in bugs.
I clean all tools with alcohol or bleach. Any soil I bake in the oven to sterilize it. Any new plants or cuttings are isolated somewhere else for two weeks to see if they are infested. Only then do they get to enter my clean room.
