I'd try to answer ya man but I don't know what EA/EN is. If they're nutes, as long as they're made for coco, I wouldn't see the problem. If they're just additives, I don't know what they are and I wouldn't know why you'd want to add em to coco. Haven't seen the need to add anything to coco yet other than A+B, Zym, 13/14, and Rhizo. Maybe everybody's just better at this than I am and they're seeing the need for something else. I'm happy with the basics so far. Easy to please and all that shit, ya know. So far, the worst I've grown is better than I ever got in the "world."
