So although the manufacturer recommended 6" or less in flower, it seems like 8" is giving me the best blending of light without sacrificing too much penetration. I had the light at 10" before and the plants all stretched to keep it 8" away and then stopped stretching and resumed normal growth. The plan now is to keep the light at its current distance from the tops, moving it up as needed. The tops have slowly begun to develop over the past few days, the watering after next will be their first dose of flowering nutes at 1/4 strength to acclimate them. I'll get up some pics in a day or two to show progress.
