Hey bandit,
I just got some auto AK's and NYCDeiselryders, so I am interested in autoflowers as well. It seems like you've been doing your research, and I am trying to keep up to date on mine as well.
I just wanted to comment that there is really no need to go through three grows before you start employing nutes; I mean, that really is thorough, but not entirely necessary.
Also, while LRs may need less nutes than other strains, they will need some; plant life just can't be sustained without any at all, at least from my experience.
All in all, though, do what you think is best.
