Just driving thru and seen you asked about stacking bud sites. There are growth regulators out there for ornamentals, I use to use one with great results, till they changed up the labels. I guess it's got alittle of the bad things in her so I dropped it myself. I used Bush Masters, and I know GH has one called Bush Load.
Here's one I'm fixing to try out. Good read. And right on the money about stacking bud sites.

Ascophyllum - Wikipedia, the free encyclopedia
Ascophyllum nodosum is harvested for use in alginates, fertilisers and for the manufacture of seaweed meal for animal and human consumption.[20] It has long been used as an organic and mainstream fertilizer for many varieties of crops due to its combination of both macronutrient, (e.g. N, P, K, Ca, Mg, S) and micronutrients (e.g. Mn, Cu, Fe, Zn, etc.). It also host to cytokinins, auxin-like gibberellins, betaines, mannitol, organic acids, polysaccharides, amino acids, and proteins which are all very beneficial and widely used in agriculture.[21] Ireland, Scotland and Norway have provided the world's principal alginate supply.[22][23]
I know a lot of people like to use a weaker form of transition fert's when first flowering. I like to hit mine hard with the P and K in transition phase. Like in the read, you only get new bud sites for the first couple weeks in flower. So it's important to make the most out of them. And to keep sites as close as posiable. Another thing is to start flowering with some MH or blue light for the first week it minimalize stretch.
I see one of them seeds is one you might have to do minor surgery to get her to open up. Keepem Green
