DBannedanswered grow question 5y ago Hi, 
You can clone once the plant is well established. 
I usually wait until week 5 or 6 when the plant it a big bigger. 
When clone do a 45 degree cut. Use an sterile knife, pruner or razor blade. Keep the growing medium moist but don't water. Use a sprayer For foliage feeding until you see roots coming out from the bottom of the pot, and keep the clones in a dome they need the humidity. 
Happy grow!!!!
