Week 3 Plant Growth Summary:
Lighting: Increased PPFD from 250 to approximately 350 µmol/m²/s midway through Week 2, aligning with recommended levels for the vegetative stage.
Watering: Conducted three wet-to-dry cycles.
Soil Testing: A slurry test on Day 6 indicated a pH of 6.39 and an EC of 2.9 mS/cm.
Nutrient Introduction: Began adding nutrients at 50% of the manufacturer's recommended levels during the third watering on Day 6. The nutrient solution had an EC of 0.53 mS/cm and a pH adjusted to 5.2. Runoff measurements showed a pH of 6.5 and an EC of 1.97 mS/cm. Optimal pH for nutrient uptake in hydroponic systems typically ranges from 5.5 to 6.5.
Plant Training: Planning to top all plants near the end of Week 4.
Irrigation System: Received all Tray2Grow components. With leaves now reaching the pot edges, plan to activate the system on Day 2 when plants require watering.
Overall, plants are progressing well, with environmental parameters maintained within optimal ranges.
