I just checked it out you have nice plants my buddy gave me these as babies and I took over this my first ever cropI always do it after week 1 when the plant is growing and stretching the most.
My garden is shown in the link in my signiture if you are interested.
Super crop. There are videos on YouTube. (Watching him pop and.twist the stems was cool. )But a tjis point it's cut or supercrop.Perfect time to bend down the main stem and tie it so its lower than the side branches. They will grow up so most of the tops are well, on top. Called lst.
You can also pinch the stem and fold over. Called super cropping.
