Trimming and topping

Do i need to trim the plant and top it? It is alittle ove 2wks old from seed. When can i top it?

you could top it
it will just grow into two... Cut it above a node
don't think it matters when you do it as long as it's in veg and the five leaf means it is

dont need to,but if u want 2,yeah,its cool 2 do it now!pizzzh is right!!

Thanks guys
