Yes you can. I'm sure there are more skilled cloners than I, but i have had success with this method on flowering cuts.

Cut clone kinda long, 2-3" away from node.
Use a brand new razor every time you clone, and wipe razor clean between cuts.
Immediately put clone in water well above your final node cut. cover entire stem but not any leaves.
Soak it for 2-5 days, change water if discolored at any point.
After soak:
Pull clone out of water and pat dry with clean paper towel
quickly razor cut at angle just below a node you can insert 2-4" into the soil pot you have prepared/soaked in advance,
quickly shave off outer layer of stalk all the way around, and about 1" up the stalk from your terminal cut
give a few quick angled slices all over the stalk(this will give many points for roots to start.)
now dip that prepared cutting into clone gel and then insert into small soil pot.
do not water at this point.
your pot should have been soaked first, then let the gel do it's thing.
place under easy lights, 18/6 or more 75-80f humidity above 40%, i dont get crazy about h% conditions, too much mold
when you see the slightest drying in 2-3 days, get the pot wet again without runoff.
7-14 days u shud have roots

lots of ways to do it, this is mine. if nothing else, it gives you a point of reference to google around, which is how i found this method. good luck and happy cloning.

Yes you can, just take a good cutting and take off the flower/bud and plant it up under 18/6 and you should be fine, bare in mind the cutting will look like shit as it goes through re-veg before starts to take off. Better off starting a seed, it would be a faster option than re-vegging.

I have no more seeds and the plants gorgeous so I’ll prolly re veg
