Whoa now! You won't be sacrificing a grow, trust me. Your plants will do better than they would if you left them alone. LST or even HST isn't going to cause your plant to hermie either. Top 'em, twist 'em tie 'em down, break a branch off, split a stalk, don't worry, she'll recover and without growing balls. People wouldn't train plants if it caused them to hermaphrodite. Hermaphrodites are almost always attributed to genetics or the plant is for whatever reason trying to reproduce with itself in a last ditch effort to make seeds.
