This is in regards to what Hydroponics is in terms of what the pH should be so that nutrients are most available to the plant. When growing in rockwool (Hydro) the pH should be at 5.8. In soil it should be 6.5 The question is, if you have something such as a hempy bucket and there is "soil" (humus and organic matter) topdressed or in the mix itself some say it is not hydro anymore, but as it relates to pH, does it matter? Does having some soil in your hydro set up change the availablity of nutrients? Like now its "half hydro half soil" so should it be at 6.1? Your thoughts blades..
