Being still a new guy at all of this and only using tap water before with my grows I am stepping into an area I don't have a clear understanding. I am getting some HESI nuts for my plants on the 12/12 grow and I am unsure of the PH down I should get with it. I see that there are PH down for flowering and growing. Do I need to get both HESI ph down or can I go with another brand like general Hydroponics ph down?
