Looks like your doing well. As always, I have to adjust my nute concentrations based on what the plant can tolerate but I've found that most of what I've grown tolerates the basic ratio's that GH throws out.
I see that it's been about a week since the flip-this is when I really start to do some defoliation, especially on the interior branches, to get light to all of the bud sites. It's kind of a dance to allow fan growth and get good light penetration. I find that once she starts to set a solid cola, I will get any fan leaf out of the way if it inhibits growth on any of the colas-at this point I want the plant to focus on buds.
