....haha I went and checked my bottles when I read your comment dude...to be really honest, I didn't check when I came back to DP....I just switched back bcoz out of all of them, I liked these the best....but I also checked the website and NPK 2-1-5 is indeed what it must be lol...I did read that they follow Liebig's Law of only the essential nutrients are needed....idk haha.... credit where credit is due tho dude, they work for me...Got me looking at Dutch Pro now... you are using coco/hydro right? Is it a mistake on the website or is the Grow really NPK: 2 - 1 - 5 ? It this N level normal?
