okay so I picked up some superthrive and haven't flushed any of the plants yet but I had one questions before I did. you said use 1/4 strength fertilizer-should I use this for both plants even though one group already has fertilized soil or should I only use it on the organic fertilizer group. And then do I just add the recommended amount of superthrive to the fertilizer and flush away? I think this will help out a lot. Thanks
