Bud Problem!!!

Well not so much problem as dilemma. As a noob, I made a few mistakes and my plants are a little behind in flowering. The strain shown is Female Seeds Grapefruit. They are on their 7th week of flowering and they are supposedly an 8 week strain. I am going to give them nutes an extra week (8 weeks) and then flush for atleast a week until they are done. Does that sound good? I have a microscope but it is 60-100x and my hands suffer from micro-tremors (shaky hands). Trichomes appear clear still, but I cant really get a clear view. Does my plan sound reasonable? Or should I just start flushing on the start of the 8th week and wait til they are ripe to pull? I don't want to cut nutes while the buds are swelling so fast, but at the same time I don't want to wait too long and not get a proper flush.

they didnt start packing on the crystals til 6 weeks in and the buds look rather small, they aremostly white hairs still. I hope they arent more than a week or two behind! they smell soo good i can't wait to try.

Here are a couple pictures of the Grapefruits. First 2 are my good plants, 3rd is a giant plant with buds that are behind the others. How far along do they seem? What will the long cola yield? Just a few questions some experts much be able to help with. BTW that is a 15'' ruler, not a 12''

what for lights are you using? Also i would not go by the breeder flowering time to strict. Due to the fact every plant finishes differently. try to go by the trichromes.All cloudy with some amber is what i like. Stop feeding 2 weeks before harvest. some do it shorter, but whatever works for you. I would go ahead and feed cause you have aleast 3 weeks. from the pics. Also the type or amount of light the plant is receiving, could also slow it down and cause thin lanky buds...:thumbsup:

i am flowering under a 1000w hps. my light is a little closer to the top of the taller ones than i'd like, but with my a/c pumping into the tent and my fans, the ambient temp is 75-80 at the plant tops at all times.

Thanks for the 3 week mark! I was thinking i was just paranoid and making another noob mistake.

I appreciate the input. thanks!!!
