Question about fan leaves during flowering.

i know at the end of a harvest the fan leaves kinda do their own thing. at what point during flower should i stop worrying about fan leaves or should i worry about em til i chop down?? the all look pretty healthy for the most part and no discoloration but at week 6 is it ok to just let it do what it does??
to clarify my question. if im in week 4 of flowering should focus on fan leaves? or can i just let em do what they do til my bud is done?

why are you worried about them if they're fine?
they will yellow as plant focus's on bud production.all perfectly normal.

thanks for the reply.. but its my first grow and i just want to know what to expect. i was gonna try to keep em green during all of flower but i didnt know if it was possible.

I usually try not to worry about mine too much after the 5th week of flowering...as long as they looked good til then I get nice harvest...It is different depending on strain...of my strains I have one that always looks pristine through harvest...she never yellows and likes to be heavily fed til the end...all my other strains start to yellow their largest leaves as they go along...but still no worries...all plants yield and smoke awesome...so whether they limp to the finish or run headlong into a harvest I don't much care.

I only remove fan leaves during flowering IF they r blocking other buds sites from getting light, and as they turn yellow, if they dont fall off by themselves... I try to limit their removal, and let them do their job of converting light energy into flower production though... Itz ok to remove them if u cant get light to other buds and if they turn yellow due to the natural N depletion that happens to all cannabis plants as flowering progresses... Too much unnecessary fan leaf removal, especially healthy ones, can result in stress and hermie-production though, so tying plants down, or training them to be out of each others's areas is usually a better tactic for providing light in shaded areas, than removal of useful fan leaves...
