this is actually a good suggestion, whenever i start a new strain, i grow the plants several different ways, some i trim some i LST some i give less nutes etc. this helps me decide what the strain likes and what it does not, therefore i know how to treat the mother and all the clones.if you really wanna know. cut off all the leaves of one branch and compare to the others. then YOU will know for sure.
but for the record if they are green dont cut them especially outdoors with unlimited space and light.
Not if they fall off on their own.Thats sounds correct if you dont remove the leaves there will be alot of leaves.
