KingLED light 1000w enough?

The manufacturer (just look at the specs for your light) lists it's power consumption as 110 watts. I like 30-35 watts per square foot so that light would be good for one plant. Leave both switches "ON" and don't bother with just using the veg and flower spectrums. You need all the light you can get. And, auto's are on a fixed schedule so you want to give it as much energy as it can handle so it grows as big and strong as possible for a large yield. You do not need to run the light until the sprout emerges above ground. Leaving it off until then will save some electricity.
