Thin plant dont mean thin yield !
Hey chron, buzz is right , just as a funny coincidence, i just supercropped my thin plants , one of my fav techniques , it will be too hard emotionally for you , no disrespect , but it involves squeezing the stem near the top, or anywhere you want
You will squeeze hard damaging the fiber till you feel it collapse practically , in essence crushing it...
Its used instead of topping or fimming , it works great , the side shoots will bulk up then the whole stem callouses up...
Try it now or next time , this pic that i just did reflects a mild version ....
Do it a few weeks before flowering...
