I honestly don’t know much about cloning, but what I do know is that thing is in flower, and cloning a flowering plant probably won’t work unless you flip it back to veg.
Incase you don’t know, the plant goes from seed, to sprout, then starts its vegetation cycle, which is where it puts on the most green growth to get as big as it can.
There are 2 types of plants, autoflower and photoperiod. Autoflower automatically flower after around 30 days, and photoperiod start flowering after they start receiving a shorter period of light in the day. Either way, when they start flowering the plant will start to stretch and get as tall as it can, making room for bud.
After the stretch, the real fun begins and you will see buds start to form like you see now!
