been running AN for 10 years and still doing well. With ph perfect, i never worry about the ph nor do i attempt to ph the nutirnets. I don;t even worry about it. it is strong stuff and it takes a little getting used to. Currently I am running my plants incoco, so I am using their coco line of Sensi coco Grow and Sensi coco Bloom, half strength (according to their nutrient calculator on their website - I highly recommend you look at this) and feeding every day, until i get a 25% runoff. My plants are very happy.
my mix:
Veg
Sensi Coco Grow A&B
AN Calmag Extra - best nonorganic cal mag on the market, imho
Sugar Daddy
Great White Myco
Flower:
