a 1000watt should be at least 5 to 6ft away from you plants. Flower you plants when there a suitable height for you but most people start to flower indoors between 12 and 21 inches
but i've just noticed your using a flood and drain table and i think most flower between 6 and 10 inches with a setup like that.
