Hey pigman,
"I will see if I can find it, where they said that the would grow under all 2700k lights" that is correct pal but when people suggest you use 6500 for veg its because its proven to be the best option, plants in veg stage grow better with that spectrum of light, here's a link to a site
http://www.growweedeasy.com/home its explains everything in one place.
Its not to late to have a good grow pal, just listen to the advice and read , read ,read, on the issue of nutes, i think as new growers we get carried away with seeing magnificent grows and try and replicate their nutrition schedule , forgetting that we don't have the same soil, lights, conditions and knowledge base that they do, i personally am going to tread very lightly with additives in my first grow,i am not trying to grow a monster yet , just keeping it alive too the end with some weed to smoke is the aim.
Here's another thread you should look at
