How and where do you trim off first harvest
Yes you can.
Each plant is different you’ll have to inspect your buds tricombs with a USB microscope for ripeness and decide what you want to chop and what you want to let ripen.
I did two plants this year. I harvested both in May. I left the bottom bud on every stalk. I feed them for veg and put them under 24 hr mid level lights. I moved them outside in July. They started flowering last month.
