Im using Miracle Grow potting soil. My lighting is 1000W sodium (RED for budding). Im using HESI nutrients for soil and I just follow their schedule with one exception; I use straight water every 3rd day. I also use molasses twice a week (1 TB per gallon). I personally feed with 250-500 MLs per feeding and I always check or set the PH @ 6.7-6.9. I hope this answers a few questions
