I need some help here, someone, please. These pics were just taken a bit ago, I just went and fed them 2tsp of cal/mag, 2 tbsp of Big Bloom, and 2 tsp of grow big. And I noticed they are yellowing, 3 out of 4 plants. PH is good, have no idea whats going on, could they be underfed? and would what I just gave them solve that????
