Hi
@Cerebral! Considering you're growing in tiny containers, I would recommend to add Cal+Mag by the end of week 2. A slight dose each week should suffice but pay attention to the early signs and increase Cal+Mag intakes if your plant asks for it. Also, I would add some more soil up to the maximum height of the container, more roots more fruits 👍 Good luck in this journey, keep us updated and happy growing 👊
