i would reccomend adding some phosphoric acid to raise the PH level a little say to about 7 - 7.2, although it does seem to be comming along nicely, i just purchased some pure blueberries from dutch passion and have them germinating, i purchased them just on the fact they said 6-7 weeks flowering, i hope its not 9, even if its 2 weeks longer, thats 2 more weeks i have to go without!
