eek 1 Flower – Light Shift, Energy Shift: The Sundae Driver Flip Begins The light has changed. The rhythm has changed. And so begins the next phase of our journey with these two beautiful Sundae Driver phenos—F2 and F3, strong, structured, and ready for the path ahead. Light Flip: 11/13 Schedule This week marks the official light flip, we’ve moved from 18/6 to 11 hours ON, 13 hours OFF. This is more than a timer tweak, it’s an intentional signal to the plants. It tells them: “It’s time to shift your energy. It’s time to bloom.” Why 11/13 and not the classic 12/12? From past experience, this slightly reduced light period tends to: • Encourage faster onset of flowering • Mimic natural seasonal changes more closely • Push plants gently but clearly into the bloom phase • Slightly reduce internodal stretching, depending on strain It’s a subtle technique for growers who want to bring their genetics into flower with intention, not just automation. ⸻ Current Plant Stats Both Sundae Driver phenos are looking phenomenal: • F2 (Pheno #2): 7 to 8 solid nodes, well-structured branching • F3 (Pheno #3): 6 to 7 nodes, evenly spaced, healthy top growth • Height: ~40 cm each • Structure: Symmetrical, thriving, ready to stretch They’re not showing pistils yet—no visible pre-flowers, no white hairs, but that’s expected. It’s Week 1 Flower by light schedule, not by physiology. The hormonal shift has just begun. ⸻ Nutrient Shift – From Start to Top This week also marks a change in the feed program. We’re saying goodbye to Aptus Start Booster and welcoming Top Booster into the rotation. • Why the switch? Because the plants are transitioning from root-zone stimulation to pre-flower induction. • Top Booster is designed to: • Initiate floral development • Begin the phosphorus-potassium push • Provide trace elements aligned with bloom-stage signaling We’re using the same measurements as Start Booster, no shock, no surge. Just a clean hand-off, keeping the biological engine running smooth. Current Feed Includes: • Aptus Regulator • Aptus CalMag Boost • Aptus All-in-One Liquid • Aptus Top Booster (new this week) ⸻ Environmental Stats – Pushing the Edge, Managing the Heat • PPFD: 760 µmol/m²/s – Measured on the TrolMaster MBS-PAR sensor, dialed in • Temp: 31°C – Yes, a bit high, but the girls aren’t complaining • Humidity: 50% • VPD: 2.23 – High, but within tolerance while waiting for AC upgrade We’re riding the edge this week. It’s warm, it’s dry, but the plants are thriving, showing no signs of stress. Their resilience is a testament to your setup, your genetics, and your love. ⸻ Looking Ahead – What to Expect We’re now in the hormonal build-up phase. The girls are about to stretch, about to signal floral commitment. Here’s what we might see by next week: • First white pistils • Stretch kicking in • Top growth pushing harder than lower nodes • Nutrient demands subtly shifting—watch potassium and magnesium uptake What not to expect yet: • Buds • Resin • Drastic shape changes That comes soon—but not quite yet. ⸻ Closing Thoughts – A Sunday Drive Into Bloom This isn’t just a new phase, it’s a new pace. The grow has shifted gears, and you can feel it in the rhythm of the room. Light is shorter. Energy is tighter. But the intention is louder than ever. The Sundae Driver girls are leading us gently into bloom, graceful, balanced, and full of promise. Thank you for following along.
