environmental factors need to be dialed in and the genetics need to allow it to happen otherwise it just wont. also good lighting.
this is probably the densest fullest nug ive grown, it was the top of my white 99 (bagseed too lol) and weighed 8.3 grams dried and cured. it was also grown under a 600w led and 12 12 from seed! i also havent found another seed (either bagseed or from a breeder) that has performed as well, ive come close but not quite lol. the finished product was exquisite.
total harvest weight was 24 grams lol.
i think your plant looks great... maybe the light could be a little bit closer because it seems like theres a lot of internodal length between your bud sites and you are only 5 weeks in id say you still have a couple weeks left at least (hard to tell from the led light being on) and youll get a nice growth spurt at the very end just before it ripens.
