Black Gold. All purpose vs. organic

Any opinions of which to use? While both have very minimal nutes in them already. the organic seem to have the less then the all purpose. so my gut tells me i should go with that. to avoid any problems with the liquid nutes i'll be using. with such low nutes in them already, does it really even matter which one do i pick? am i seeing a problem where there is in fact none. should i not have to worry which one i use?

thx for the feed back.
