My 3 BOG was a weird grower. She was slow and small at first the other girls blew her out the water. Then one day I open the tent and she doubled in size damn the next bigger again. She grew more like a Sativa long side branches as high as the main. No training at all. She was like a weird yellow green then green then yellow finished red so idk. Other girls were all on megacrop also and stayed green till harvest pretty Much. Day 52 seems a little early to start the yellowing increase feed a touch maybe.
