Soy Larry, OG de California

So they are growing like crazy. It is my first coco grow, so im having trouble dialing in the cal mag. I went 2 days without adding this past week to see how they responded and I saw calcium deficiency, on day 2. They look great though. Really bushy. I moved the light up and increased power to 50%. I plan to up pot and then start slowly increasing to 75% until I flip. Also I topped them again. I didn't think id do so this soon, but they were ready and I topped 4 sites per plant. Im hoping for a nice scrog canopy by mid to end Feb.
