I am using the Advanced Nutrients 2+ Bloom (medium feeding) program. I continually give them 2 feedings of nutrient (at 6.3ph) and 1 feeding of regular water (at 6.3ph). I foliar spray with Growth Excel just before the lights come on about 2-3 times a week (tho I dont PH the water I use for this foliar spray - should I?). They are growing in ProMix HP under a couple of 1000 w HPS's. Temps are between 17c/65f and Rating: 5
