I have done it a few times. I ran 1 plant 3 times to see if could keep it. Still have clones from that plant.. I know exactly where you are coming from. Here are two ways I did it:
Harvested the plant except for a lower section with small leaves not just popcorn buds. You want green. Carefully cut off small buds, if any, leaving leaves only.
Left it overnight to make sure it didn’t just die.
If the bottom section with green leaves looks alive enough, cut the stalk 1/2 inch above highest green leaves and cover cut stalk with a fresh piece of frog tape or painters tape, make sure it’s sealed and trim excess carefully.
*tip 1- You don’t want your re-veg to happen too high up.
*tip 2- It’s always better to look for a node, junction or knuckle that might spring forth multiple tops to grow or use as clones.
*tip 3- it is important to clean up areas you cut on the stalk that might house insects or other funk. Do not let cut pieces hollow out, cut them back cleanly.
SOIL
At this point the soil should be depleted and / or flushed after harvest. That is ok to start re-veg at 18/6 light, and plain water. At the fist sign of growth , diagnose the soil needs so you can grow it out or take a clone and start fresh.
New growth will look odd and be mostly one bladed leaves of different shapes. Teardrop shaped then a blade.. Don’t worry. After a node or two it will normalize to usually a weird 3 bladed leaf. Take clones after you see 5 bladed leaves. When I took clones with 3 bladed leaves it only grew 3 bladed leaves for a long time.
THE SECOND WAY
You can do it without cutting the stalk if you have room to train it horizontally (after cutting all the buds off.) Put it in 18/6 light and the new shoots should come up vertically from the horizontal stalk. If it won’t bend all the way, you can bow it. Just think about your lighting situation before starting too tall for your space. This way I just let it grow and flower. It had new shoots at almost all nodes.
Hope that helps.
