what you did will work ok looks like 3 sets of nodes to grow up View attachment 3325563
yup looks good.
you pretty much cant fuck up topping a plant. cut it anywhere at the stem and it will split. but you did it perfect. how often you top it is up to you. i usually top every couple weeks but it depends on the speed of the plant growth. i would wait till you get a few new nodes from that before you think about topping it again.
