My vote for you would be Dutch Dragon.....easiest grower of the three considering your work schedule....and that would be a GREAT plant for something like a port o scrog.

Second choice would be the whiteberry....then Master Kush (the MK's can be a bit fussy as seedlings then seem to do really well later)

I found Blueberry to be kind of a pita and WW....VERY light feeder so a bit of a balancing act.

That is THIS reporter's opinion.....
