Flowering stretch.

I would brace for 100% stretch, since you flipped it. Different stretch for different strains. Some sativas can stretch 200% The stretch has no bearing on yield, if you have plenty of branches. Sativa yields less than Indicas or Hybrids, with same height, keep this in mind.

Hey Growmie, Normally the plant stops stretching in Week 4 of flower and starts focusing on fattening the buds, but just because it's still going doesn't mean it's going to affect your harvest, it just means your going to have a monster plant and possibly a monster yield. Hopefully, I answered your question and remember ..."Happy Growing" and "Free your mind one puff at a time"
