Well, I've confirmed through sources that we officially entered the flowering stage as of last week. Time for some adjustments. Just prior to confirming flowering, I did one last trim, removing the larger fan leaves at the top to allow more light to the bottom. Good thing I did this now, as any later I've been told will shock them too much. With confirmed flowering, I switched over from both blue and red lights to just red. I also lowered the lights closer to about 9 inches after being assured that they won't burn the leaves any. With the transition, I gave the plants one last watering with the N-P-P mixture.
