Nutrients in the water or not, you water the same - enough to saturate the soil and make it moist/damp. NOT wet. Also I recommend feeding only reduced strength feedings, especially to growers like you to prevent nutrient burn. But I'm betting you do anyway. I just finished growing almost 20 autos - a mix of Sweet Seedss Big Devil (what a lamer those are), Paradise Vertigo and Dinafem White Widow Auto. I also grew out one WWA in a 5-gallon DWC and here is what I discovered - autos do NOT like nutrients, at least at 50% feeds. A full strength feed will fry them I will guarantee. What jokes, screw autos. The DWC plant - the PPM got above 300 one time and burned it. 300. It liked the PPM around 250.
