Durban Poison Feminized ScrOG grow

The DP seedling is growing well. 1 week from seed and working on leaf set #3. There were roots growing out of the bottom of the peat pod, so she is in a quart container. 1 scoop of composted super soil followed by a 50/50 mix of Fox Farms Happy Frog and perlite. I plan on using the ScrOG grow method and will be topping as soon as I see leaf set #5. It’s been 4 days since I planted the Blueberry seed and still nothing. I’ve started adding a capful of hydrogen peroxide to the water to counteract the green on the perlite
