Trimming

In my experience trimming methods depend on strain, I always advocate minimal trimming and more training/tucking, the plants response will depend on strain, I also like to trim fan leaves off the bottom when they start to Die, it helps the plant conserve energy and opens up air flow

Trim away mate. It encourages more growth and lets the light in. If you haven't done it before, don't go overboard, you can't stick them back on. Keep it even, & use clean equipment. Good luck, & don't forget some pics

Hello Vindollar in general we don't defoliate with auto but you can defoliate just a little to bring more light on lower bud sites. Don't defoliate too much because it is a stress for your plant. As you are in 3 rd week of flowering you are in the good window to do your defoliation. Good luck. Bye
