First one is 2 big, second is to small, 3rd one is right, got 2 different phenos of 1 strain and did not know for shure what largest plant was till it grew, will not take bloom nutes not even a bitty bit, don't mind pruning, pH was high got down to 6.2 to 6.4 some were over 5.0, so just cut light cycle to 12/12, only thing you can do, give a bit of fresh perlite. Check pH, this is what happens when I break my rule of running multiple auto strains, the largest plant forces you to raise light, then you have to put crap under smaller strains, smallish plant and middle plant are 4 aseed monkey by Meth the big one is cream carmel by Sweet Seeds at day 63 from sprout.
