Are you growing from seed? If so then maybe the one growing faster is a male. That's usually how I tell a male from a young age cuz they will grow more vigorous but if it's a clone or fem seed then disregard that.
Maybe this will explain better how the G13xHaze was:Noice Slanty+Rep for those..."Learning How To Roll" my ass lmao Btw, how was that G13!? I only assume it was amazing, but ya never know. I dig the screen as well...nylon fiber yea? 2" x 2"?
You will really have a crowded screen if you wait til the screen is mostly full before you flip. 2/3 is ideal. Trim out a bit of the fan leaves and open up the lower buds to more light penetration and you won't have as many golfballs. IMO
