I do the same but rather than stripin the branches i just remove the branches, you get better results i just ran pe with this method 1 Top and the 4 main branches and that was it, i ended up with a fooT or so lonG main cola as fat as my arm,,was imPressive, im a lollipop convert
just looked at your week 4 images
i will say tho u did go rather extreme i think ur not gunna get the yeild u expecting. shame but it will be dence nugs at least..
them pots your using seem rather small, i think u went over the top with the trim and should have done it last week of veg, in my opinion
