yellowing before harvest... why is it good?

Hey guys,
My plant is about 5 weeks into flowering and i am going to have to chop around week 7 for personal issues. I have decided to stop giving nutes 2 weeks in advance (besides molasses) because i have heard somewhere that the plant can use up the energy from the fan leaves. Can someone explain to me why yellowing before harvest is ok? its kind of hard to watch my plant turn yellow without doing anything to help. heres a pic, its getting yellower by the day

Its just the normal progression of the plants life. Its dieing so the leafs turn yellow.

the yellowing is from lack of nitrogen. You arnt giving it food because you are flushing. It is ok to flush and not give food if you are in the last weeks of flowering...

The yellowing is the natural course of the cycling plant. To promote better quality of flowers it is best to reduce the amount of nitrogen but at the same time increasing the amount of phosphorus dramatically. When yellowing of leaves occur in the flowering state, you are bleeding nitrogen.

its using up all the nutes its got in it, its a good thing for sure,
