looking to clone

I have a two month old clone and i was wondering when i could maybe start taking clones from it.

d'ya know anything about topping ?

Honestly I do not even know what that term means...

You need to do a whole bunch of reading and watching youtube vids.

I have been researching as much as i can and i know how to do it but i just wanted experienced growers advice straight from them on when it is ok to clone a plant and how exactly should the cutting look? Like how many branches leaves etc.
