Brother, do not shoot the messenger, I was just relaying the info. LOL I am sure this may have something to do with it, I do not fertilize many lawns anymore, but I used to use and still do on my own lawn more K than N in any given feeding. The blends I use also contain at least trace amounts of some of the micros. The result I have gotten is good color, without excessive growth. I agree with you on this point to.
