Supercropping, scrogging or putting a net on it, lst etc are ways of dealing with the stretch as it happens. Youre past the stretch from what i understand, and you already have some budding. I dont think they will grow any taller. Supercropping would just be for the sake of doing something and imo not necessary in any way. Now you should focus on
- increase light levels if your not already on max. But do it real slow and soft, looking for plant stress like purple stems or leafs fading to light green to see if you gone to far. Another strategy is first 1 hour on high and then back to where you were, next day 2 etc, evaluating as you go along.
- environment: important to not get mold and stuff and also for growth. Keep temps up between 81-84 and RH (especially at night!!!) from getting going much over 60. Also some extra aircirculation would probably be good. But nit the plants trashing in the wind.
- bloom nutes: if you wish you can ad some bloom nutes or pk boost but be carefull its it easy to burn your plants.
As a general advice less is more, dont love your plants to death.
