As others have pointed out clones can be taken from clones without deterioration, contrary to a popular myth.
I’m cutting bottom branches from my veg plants everytime just before I switch them to flower. Some say that lower branches are weak, bud look above how nice and strong ~15cm clones I take usually.
This way I get a lot of clones “for free” additional to what I’d get from a mother plant. It also helps to make proper airy environment in lower layers in grow tent. Bare stems allow air flow just above soil (coco) level. This helps to prevent from mold later in flowering.
This is how it looks when I cut lower branches.
