This week marked the second week of ripening. Light intensity continued its gradual decline over the past 7–10 days. At the beginning of Week 13, the canopy received 640–700 PPFD (DLI 28–30), and by the end of the week, light levels had tapered down to 550–600 PPFD to signal the approaching end of the cycle.
Ripening nutrients were applied throughout Weeks 12 and 13, with the final plain water flush scheduled for Week 14.
Water uptake slowed noticeably this week. I adjusted accordingly, alternating between heavier waterings of 3–4 liters and lighter days of 1–1.5 liters, depending on plant needs and pot weight.
