so, you plan on keeping them in flower till they do as they are told? the plant has a sort of built in timer, you can stall out veg state, but you cant really tell it to flower longer. the little beggar just doesnt have the programing for that. you might want to try some research on plants in general and cannabis in specific.
have you considered the stress your training might cause in flower stage? doesnt that often cause hermaphrodites? that might ruin the whole show.
ok, so... many here have tried to help, but even with the lights you were rude and just had belief and some bad lighting to back you up. they tried just telling you their experience, then they tried science, persuasion and cajoling, to date nothing works with you. you can plan on making a tomato plant act like a cucumber, but you cant ACTUALLY make it do that, you can want and wish and even try foot stomping and insults, but these guys, the ones with YEARS AND YEARS of PRACTICAL EXPERIENCE and EXPERTISE, seem to be telling you many things you just cant seem to grasp, among these things, but not limited to, they are telling you that what you are doing is not effective, efficient nor how plants really work. but you know... well... you know what you know and forget the rest. forget science! forget mother nature! you want it to be so, so like the king of siam in the movie - so it is written so it is done. but... the teacher lady finally got through to him and lincoln kept the elephants
