Hey Tee,
Just read through your journal and have a few pointers for you.
Firstly Root riot cubes are almost failsafe for germinating your beans.
Leave off the miracle grow, I know lots of people use it but IMO it is too "Hot" and really complicates things when you start to add your own nutes. I find a light mix perfect for the short lifespan of Autos. (Bio bizz, Plagron etc.)
Give your auto's as much light (Heat permitting) as you can from day one, they will reward you for it.
And Im sure you asked about "which" nutes to use somewhere in your journal. I your gonna use bio bloom then I would definately recommend using top max for that extra yield as I find bio bloom on its own doesn't quite cut it.
I look forward to your Auto Ak grow dude, good luck.
Trickky.
