Seymore is over 6 ft tall has 20+ buds and is 13 weeks old. Help please!

Seymore (from "The Little Shop of Horrors") is my first grow of any kind. Not knowing what I was doing, I never topped it and I guess I let it stay in its "grow" phase for too long (8 weeks). At any rate, despite its name, I'm pretty sure its a female. Most of the buds are acorn size or smaller although the main one at the very top is about the size of a half of a bratwurst. I started it in its 12 on 12 off phase in about its 8th week and it is very slow to bud out (its strain is Blue Dream)

So I guess my question is what do I do now? Do I just chalk it up to experience and try to harvest what I have? Do I keep feeding it and hope that all those buds get bigger? If I harvest it what do I do with all those little buds? Where did I screw up?

By the sounds of it mate, shes only been in flower about 5 weeks... I have no experience with blue dream but at a minimum you will need to leave her 8 weeks, 10-12 isnt uncommon. If I were you Id look at some other information out there on when to harvest. You didnt screw up mate, Ive trippled or quadroupled my yields since my first grow... its not just one factor, its a whole host of things which ive picked up from trauling through forums basically. If you leave a plant vegging for that amount of time, you want to make sure you train your plants to maintain large, dense buds whereas if you allow them to get tall and scrawny you will end up with popcorn buds, keep feeding her for the time being, dont over do it though, twice a week should be fine. your buds should enlarge and become more mature over the next few weeks so dont harvest just yet.
When you do harvest, hang them in a cool, dry place with lots of air flow... your first homegrown smoke is always the most satisfying. enjoy.

Oh really? Well that would be great if it keeps going, I'm only feeding her once a week, so maybe I'll kick that up to twice. I'm really looking forward to the harvest. Thanks!
