Simple Hybrid

Today is day 15 of flower. My big girl is out of control. I wanted to maintain an even top on her, but have not done a very good job. I haven't done any defoliating except dead leaves this time around, I'm not sure if it makes a difference or not in the health of the plant. So my dilemma is should I super crop again to even up the canopy or is it too late? I think I'm missing something about mainlining. I still have way too many branches that aren't even getting 200 ppf and the top of the plant is getting 900 in some places. The other 3 girls are growing great all in final pots and ready to make buds. Untill next week happy growing!
