Don't want to argue
but you can go get any book on botany or horticulture and learn the reality or you can simply keep passing out myths and folklore,,,,,,,,,,,,,,,,hey it's your bud, your smoke,,,,,,,what you do with it is your choice???
but for Noob's reading this let me explain in terms that are easy to understand, most all of us have cell phones, in order to use them we have to charge the battery. Once the battery has given up all of it's energy, it is DEAD
Until we recharge it, then we can talk again or text or surf,,whatever
On our plants, the fan leaves are the batteries and they store energy for the plant to use in "its" processes (one being bud developement) The fan leaves need nitrogen to continue this process (recharging) if there is no N in the medium the plant will suck it from the fan leaves and effectily kill them, leaving them DEAD and UNABLE to recharge
What this effectlively translates to, once again using our cellphones as a guide would be like having no bars left on your battery and knowing that yoiu can only talk for a few more minutes before the phone shuts down
Once all of your fan leaves have turned yellow and died bud production effectively SHUTS DOWN, thats is as big as they are going to get
keeping the leaves green by adding N during flowering means that they WILL RECHARGE and continue the processes that make buds grow
rather than argue the point I will happily conceed if you can show me just one ACTUAL gardening, botany or horticulture book that says different?
