yea i mean im not disagreeing on the soil thing. It should be good for awhile your right. but u can start earlier with the GO box. I did and my plants loved it. Compared to other peoples grow around my area with same soil diff nutes mine ladies were double theirs. I mean if u can give them nutes why not? the earlier the better(roots will develope quicker etc). I would say around the 2-3 week period you should start the nutes. !BUT! and i cannot emphasize this anymore, it all depends on how big the plant is. THe bigger its is the more it eats obviously. So time doesnt matter so much as size. Jus like humans. But yea dont get me wrong im not saying your wrong on holding off on the nutes, just saying it depends on the size and roots more than a time frame as different strains grow differently.
