I appreciate the input. I've done a ton of homework too. If I do go with a light then I'll do a dual 400w - 600w and only run the 600w for two weeks during peak flower. But I'm really more interested in an all LED grow if I can get it done right. And if I need to run the HPS for a few weeks then so be it.

But enough of me. I did not set out to thread jack Moody's log. Sorry Moody! I'm more interested in hearing how you did with this grow, and to learn from your experience. Can you give us some more info on the coco/soil mix? What proportions? Any other amendments? Did you use perlite as well? Any other amendments? Why do you think this mix helped? Besides the coco/soil mix and the shishi high end water, what other steps did you take to dial it in?
