tone,
I think your plant is looking pretty good. The watts per square foot your are using is 66. That's not the optimum you see quoted here, but well within the range that is quoted for a successful grow. 50-100 watts per square foot seems to be quoted quite a bit. Another measure that is mentioned is 100 watts for the 1st plant.
What caught my attention is my grow watts per square foot is 65, so we're lock in step on that score. I'm using 78 watts in a 1.2 square foot tube. 2 weeks into flower, so I think about 1-2 weeks behind yours. Ways to go, but things are looking ok, we'll see where we end up. Best of grow luck.
