My Jock Horror does that. I think, at least for Jock Horror, that's just the way it is. It hasn't seemed to harm anything: yield is fine, taste is fine, potency is fine. So I just quit sweating it. I figure if I start adding this nute or subtracting that nute, that will likely lead to me doing more harm than good, and since it's caused no problems, I'm not messin' with 'em, personally.
