A buddy of mine grows GG4 and has for awhile. He shortens his veg times, Runs a 4k light in veg which has more blue light so keeps plants short with real tight node spacing, he supercrops on day 1 of flower and also pinches the tops of every branch he bends down, during stretch he keeps close day/night temps, defoliates at week 2 to slow them down. He just started foliar spraying with an concentrated mix of Power Si and he said the Silica foliar spray kept his plants real short.
