Exclude the bottom two internodes not including the cotyledons. Give your self two or three or even four internodes still in tact (leave that to your own discretion) make sure you don’t cut the new branches coming in above the fan leaves, and snip at the stem leaving about 2-3 mm of stem still in tact above the internode. Good luck sir! I hope it makes sense. Go down to my journal for a reference from the pics I posted last night.
