It's week 5 of flowering (week 9 of total growth) and my buds still have mostly white hairs (and they're not very big either... I forgot to add photos with a size reference). Maybe the whole thing is taking a bit too long due to the low intensity light; 150W is perhaps not enough. I'm already thinking what to change/improve for my next batch, so far I have: (1) increasing light intensity, (2) keeping no more than two plants in my narrow grow box (right now my Tropa de Elite is growing next to two Girl Scout Cookies), (3) use a larger pot (now I'm using a 7-liter pot, I think), (4) controlling the height and evenness of the branches; as you can see in the photos, I only have one 'big' bud on top, whereas the other buds are significantly less developed (see last photo and video).
Overall I'm pretty happy with how this is turning. I've finally caught up with my posts, and now I really don't know what I will be posting next. Hopefully good news.
