<span class="link_user">@LightATree</span>, Thank you so much for commenting and trying to help me! My pH is controlled since day 1, I have a pH pen and I always ensure it's between 6.2 and 6.5 after adding nutes! I don't measure runoff, so I don't know what's my soil pH honestly. I'm confused on how the left one could be having N excess, I'm saying this because she has a lime green color, which should be the opposite according to my understanding... I was thinking of just increasing Bio-Bloom during next feeding, but now I'm unsure. :(
