now now chowder, I like my chem's...hey, one thing to remember, unless it is a tea as Marc suggested, you shouldn't use nutes that have been mixed more than a week...I find that the ph changes drastically during that week and the effect of all the nutes and additives doing there thing over that period of time can make them useless..
This is advice that I got from my Advanced Nutrient Gurus in Cali...oirganic is safer I guess...good luck bro.
