flowering for over 2 months

my 4 girls are over 6 feet tall and have been flowering for more then 2 months...the top nugs are fat and almost all the hairs are red...the bottoms are much smaller and only half the hairs are red...can you let the plant flower for to long before harvest...they are purple #1 but only one plant has a little bit of a purple tint to her...should i wait longer

simpale anser yes thers a point when the thc starts to drop but from wut iv read the most importent one is the top (contanes the highest thc ) so i thnik yors wud be ready but i have no experence in budding yet still never got that far yen its mosty book knowleg (note i only repeat if it wut i was reading or waching proved concept and some dont but thats wut rashinaol thought if for) but wut ever you chose to do i hope its good

From what you say about the top ones, there ready. Cut those bitches off. Leave the rest to finish.

I would wait... maybe 2 more weeks. Can take up to 12 sometimes. maybe wait 2weeks and take off the tops. then let the bottom go 2 more.
