California snow #²

Hi there, I see you kept your light at 50cm most throughout the grow. Did you measure light intensity and if so, at what percentage did you set your lights throughout the grow? Here I'm keeping it around 60-70cm and moving from 25 percent to now 50 4th week of veg n moving up to 85 by the end of the grow at about 60-70cm height. Thanks for your input anyway!
