ello m8 hows it going
look at ya plant and and take the clone off a healthy stem that looks quite thick cut it at an angle too to help root promotion in the clone
then if there is a few leafs on that clone that look like they will be to heavy just snip half of them off leaving a bit of foilage on it
then take ya new clone and gently shave a lil bit of the bark off the bottom wher ya sniped it this will promote root growth too
then dip the shaved part of the clone in water then into rooting hormone powder and/or gel this will give it a better chance of makin new roots then plant it into ya soil sinking the shaved part in about a half inch into the soil
then give it a nice watering and leave it my friend
and let nature do the rest
hope this helps
