I only used just floros for the first 7 days or so (24/7 light till they sprouted), then they went under the 2 mv's ( I am using 1 mv lamp at 4000k, 1 hps at 2100k and one mv at 5900k, the only bulbs I switched for flower was the 4' floro tubes, went from 4000k cool whites to 3000k warm whites) with 1 hps and 2 4' floro tubes. you should use cool white (or DX cool type) for veg and warm white (or kitchen and bath) tubes for flower. mind you my plants were only vegged for 33 days (under hid lights), i'm now 10 days into flowering, my total lumens are 45,800 (what they're under now) all four remaining plants I have are passing the 23" mark by tomorrow. you should definately get as much light as possible to those plants of yours btw.
