I grow in coco too and I also use a non coco nite. I run flora trio mgb with liquid koolbloom big bud over drive and botanicare cal mag.
I agree with unique. I like to make sure my ph is spot on before watering my girls rather than trust a product that may or may not work.
But as it was mentioned above nites are more of a personal preference than anything. You have to find a brand that appeals to you and claims to do what youre looiing for it to do. Dont buy because of a brand name or because 1 person tells you they got a pound with a certain brand, nutes are pretty much the same thing, different companies make you pay more and some make you pay less. Just depends on which direction you want to go.
