From my research and the way I grow the ppfd never goes above 690. 800 and some is too much light. Remember your not at 12 hours of light I am assuming your at 18 hours of light. Means more light per day and autos can really be sensitive. Just from what I have encountered. Leds use energy flowing across a chip to produce light . Hps heats and pressurises  gas to obtain light. ... so leds take less energy to make bright ass light. Plus light increases should take days or a week to get to the brightness you want. Too much at one time is not good for anything. Remember when I told you becareful of stress . This is the reason I chose yo wait to a new grow to hang the new light. You also have a full spectrum of light so it is like running a MH and a HPS at the sametime.
