Yep. Plants are basically still growing vegitatively during the first few weeks of flower while they are stretching.

You dont eliminate N in flower, especially during first 2- 3 weeks of flower, just drop it a bit once flowering starts, we will go with less N and more bloom nutes.

Yeah, even in flowering, I still add 1/2 tsp of GB to my flowering mix all the way to the end of week 7! And that is if she is in FF OF, but if she is in FF HF, then I use 1 tsp of GB instead of a 1/2 tsp of GB.
