Haze Berry Automatic / micro grow

I gays in this week, unfortunately, I broke an apical branch, but I fix it end now the plant is safe. The plant is growing super fast with big leaves, she is healthy no strange spot or something else. During this week I chose to add a bit less of nutrients, because I saw the leaves a bit darker. The humidity ranges from 45% to 55%. I continue to keep the fan inside at the grow box in turn on all day, for the continued air recirculation. I continue to apply low-stress-training to keep the plant as low as possible because the grow Is super small I begin to feel a bit of perfume from the plant. I check the PH with the tool that I show in the photo, I calibrate it for only 2 weeks with a precise solution.
