Week 20 marks a transition phase for the Pineapple Upside Down, and the plant is now one full week into her new environment. The light cycle remains unchanged at 12 hours, and nutrition stayed stable. However, the major shift this week was the move from a 5000K veg light to a 3500K full-spectrum panel. This immediately triggered a visible reaction: the leaves, previously flat and perfectly extended, curled downward, showing a clear photonic stress response. Structurally, the plant is beginning to adapt. The earlier LST work is starting to show again: the tops are lifting toward the light, suggesting that she is reorienting herself and gradually regaining balance. Externally, the structure indicates a slow recovery, even though internal metabolic adjustment to the new spectrum will take more time. All environmental parameters were intentionally kept constant: – PPFD maintained at 550 after a 72-hour acclimation at 300 PPFD, – Temperature around 23°C, – Relative humidity near 70%, – No changes in nutrient formulation. This week’s focus was stabilization rather than growth. Given the current signs — partial recovery of the tops while the leaves still show stress — the plant will not be flipped to flower until she demonstrates a clear return of vigor. The upcoming week will be key. If the foliage regains posture and the stress diminishes, the transition to flowering can be considered. Until then, the approach remains minimal: no corrections, no boosters, only patience and consistency. Week 20 closes on a cautious yet optimistic note. The plant is stressed but responsive. The next phase will determine whether she fully adapts to her new 3500K full-spectrum environment.” Peace,,,
