Base nutrients, not sure what else to say besides you need some form of Micro, Grow, and Bloom. The RapidStart though truly works and made my roots HUGE. You can 100% tell a difference between a sprout using it and not. Insane root growth.
(((I do NOT know why GrowDairies has changed the nutrients from the General Hydroponics Micro/Grow/Bloom to this, Terra Aquatica nutrient?? I did NOT use TA, I used GH)))
