Thanks for all the comments! I appreciate all different advices, but Homebrewer it would be nice if you could include more specific details as to why you are arguing with such conviction.
The way I see it, we are trying to grow cannabis strains indoor which normally grow in a tropical environment. Even assuming we were able to grow them 3 meters high with 1000+ Watt of light, then we still want the plants to flower and give a yield to harvest. If we would grow them under "perfect" conditions with high N-nutrition, then they would just never finish. (I set marks aroung perfect, because I see it similar to all those nutrition recommendation to humans, they change and vary a lot!)
Even assuming that giving them a lower N is "bad" for the plant and hence not perfect, it would still be the best way to handle it indoor because it is better to have a yield which may be less, than in theory a perfect yield by handling the plants perfectly, but in the end giving no product at all because the plants feel so good they never end flowering.
Sometimes plants need something to trigger them to feel that the end is near so they produce flowers.
This is similar to a lot of plants in the norther parts too, where there are different seasons. Believe me the winter season is not a "perfect" environment, because plants stop growing and losse all leafs because of that. Still exactly that is necessary, those plants need this winter break otherwise they would die if you would grow them indoor without a simulated winter.
It is a common method to cut apple trees when they dont produce any apples. This is "bad" for the trees but triggers them to flower and hence produce apples because they want their genes to survive.
