I do not have any experience with blueberry, however I have been growing O.G. Kush from clones for around a year now. Both indoors and outdoors.
I can tell you that O.G. is easy to grow, and easy to maintain. I've grown both indoors ( in soil ) and outdoors in the ground. O.G. clones easily, is very forgiving on the nutes, and grows very bushy. I topped / fimmed mine to encourage multiple colas with very good success.
The only problem encountered was a brief bout of spider mites, from which they recovered well after treating them.
For nutes, I make my own tea out of worm castings, molassas, blood and bone meal, bat poop, and azomite. They don't appear to need much beyond that.
Pictures of my O.G. that I planted June 1. They where aprox. 12 inches when I planted them and they are now around 5 ft. in height as well as 5 ft. in diameter
