Well for the moment, it's a little late to be mainlining so you are kinda limited to what you can do, as for topping, you are not there yet. Height wise and where she's at, what you have done, you will have enough height for sure. Really impressive LST skills with that alone a guidance into a nice bushy but decent size, I'd start training her a little up now tbh to get lager areas for bud expansions, she's looking a little crapped, but that's just down to having her tied down and you have her that way for your own style, which should always come into it, photos are great to mess around with much more forgiving in swing temps/def/tox cause u have as long as you want to keep her in grow. But yeah man, she's looking great. Train her up she'll stop putting on stretchs, well big uncontrollable ones now u got her in flower.
Happy growing, good luck!
