Big Eggy is right. Get some fluros for the Mom and clones. Get enough so you can veg to say 18" in 4-5 weeks and keep the 2 400's for flowering.
Go with a soiless mix and add Botinicare and Mycostop to your resevoir, use good liquid constant feed ferts set at about 1,000 ppm in flower and make sure the pH is less than 7 and a tad over 6.
Out here on the periphery, there are no stars...
