how long should i flower bluberry

ive been flowering for 6 weeks now, im just wondering because i heard if you let it go to long theres a chance that the thc deminishes,and my buds are orange allover,it seems that there is no more white hairs and hasent been for quite some time,the plant has been rock hard and stinky and probably 1 week ago it started to lose its smell quite noticibly and 2 days ago the buds went from rock hard to soft and sponge they feel like a tooth does just dangiling before it comes out the stems are intact just really soft and bendy, is this a problem. and how long should i flush before harvest, and i have (i know its not idealistic to do so) some sativas growing thats going to be in the same res. while i flush ,and they have another 6 weeks,is that going to be a problem for me.

Q. How long?
A. Probably for a total of 8-9 weeks. Blueberry is all indica (maybe a little sativa, depending on the specific strain) and will finish flowering closer to the 8 week mark I'd imagine. Make sure you have something with strong magnification (good camera, 25x magnifying loupe, etc.) and check your trichomes; you will want them to be mostly milky white and not completely clouded. This should also be when most (70-90%) of the pistils have turned dark and are a nice deep amber.

Q. How long should I flush?
A. About a week. Some people do it longer, some shorter, but a week.

Q. Will the 6 plants still growing be a problem?
A. YES! If you have them in the same reservoir, Your remaining, growing sativas will be deprived of nutrients for the week that you flush. Find a way to separate them for the flush week, or don't and lose a week of growth. You should try to separate your plants based on nutrient cycles so that you do not run into this problem again.

thank you ill just have to get all of the same types next time

what kinda system are you using you should also post some pics of the beauts

You shouldn't harvest by taking into account the hairs.... the trichomes are a much better indicator (clear/cloudy).

:)

well i messed up royally i foilar sprayed and the buds were so compact that the water got trapped and the 400 watts hps created codensation and i checked my plants the next day and they were so wilted and completlet lost its firmness it was like a tooth dangiling on by a root so i thought that it would just dry up and be okay but checked the next day and it was curled up and really crunchy i mean just brittle it must of burnt the thc because it smells like lawn clipping instead of blueberry like it did. its not sticky anymore so i have 1 and a half weeks so im pulling it

Pictures?

before the mess up

oh and one more question theres this seed i found and i use it for my first harvest here is a picture of it. anyways i pretty sure its sativa but not knowing exactly what percentage ind/sat it is i dont know how long to flower it,now the first harvest i didnt flush and pulled it at 71/2 weeks the taste was like grasss clippings. this time its been 8 weeks and ive looked at the tricomes and there are cloudy ones all over and if i turn my hps off and put regular light the hairs are about 50 or 60 percent orange and ive noticed amber tricomes on some places around the sativa wich is a clone from the first harvest. so any input on when to pull it would be great thank you.

heres the pic from last harvest at 7 1/2 weeks
