Have not tried those dr earth, but im using dr earth compost and dr earth pot of gold and home grown soil mix with spectacular results in veg cycle...i plan on using dr earth organic #8 for flowering, right now im growing g13 pinapple express,blue og, and a strain i been working on for 8 years that i havent named yet. I think people are wasting a ton of money on liquid nutes as they only offer the minimum....its all about the soil...alwAys has been.......feed the soil.....
