I can't believe 5ft plants in 2gal pots aren't root bound already. I had plants that finished smaller than that and almost filled a 5 gallon to the point of being root bound. Lookin good, just dont get your hopes up too much. My last grow a couple friends and myself were guessing what yield was on a particular plant at harvest time. We were all way off. The plant was over 4ft tall and covered in buds. The cola was bigger than a coke can. It gave me a little over an ounce dry. The closest guess was 2 ounces off. They look much bigger wet. Keep it up.
