seymourbud, you may be right to be cautious about re-potting. Like bootz says the Bb is a faily light feeder so you may be able to slow down the fading with some simple organic bloom nutes, i would use half strength maybe every other watering for the next couple of weeks.
bootz has given you some good feedback. the only other thing i would add for brown spots - it can mean a lack of oxygen at the roots so make sure your plant is drying out a bit inbetween waterings and perhaps add a little more perlite for next run if you think this might be the problem.
i also agree that a slow fading from the bottom of the plant isnt too much to worry about - and i would add that the best quality smoke often comes from the plants that fade out and yellow out the most spectacularly. after around 5-6 weeks i am hoping my plants are fading and worry if they arent! its often dictated by genetics as well as nute availability and rootbinding.
the worst thing you can do is aver-react and add too much feed at this point.
blueberry is notoriously sensitive to environment and feeding - not all of them but some. its the sort of strain to try when you have your grow space and style 'dialed in'
