Flowering Fifth Week

hey guys i have a question how many fan leaves are needed to finish flowering i am losing a ton of fan leaves they are yellowing and curling off and i kno that that is naturally for a lil bit but i was wondering if i end up losing all my fan leaves will my plants still survive the last three weeks?

Any input would be much appriciated thanks guys.

I don't think that its a good thing that your fan leafs are fallin off but it won't kill your plant if that's what your asking.

if you are losing fan leaves like that something is very wrong and can kill your plant
