i have used Earth Juice in the past and have found it to be problematic. first of all the PH is way low and you have to put it in a recirculating res to activate the nutrients. once the res has been circulating for minimum of 24 hours you have to pour the stuff through a strainer to get the clumps out. then you adjust the PH and then you can water your plants.

i suggest using BioBizz nutrients; they are 100% organic and easy to use; i have been using them for the last four years. all you have to do with them is add a tbsp of your selected fert to water and the ph will be at 6.5....its that easy and i've gotten the best results.
