Pfluk

Nice plants! One question, why do you add ph-? If you add a lot of nutrients doesnt that also lower your ph? I also use BioNova, pretty much the same as you but I had mutiple plant that seemed to have a cal def, which led me to believe I had a too low ph for cal. But the drainage always stays between 6 en 7, the same as the water/nutrient sollution. Normal tap water here is a little above 7.
