Week 6 Cannabis Cultivation Diary Entry
Growth Stage:
Week 6 of Flowering (Autoflowers).
Plants are progressing into mid-to-late flowering, focusing on bud bulking and resin production.
Environmental Conditions:
Temperature:
Maintained at 24°C consistently.
Humidity:
Lowered to 55% to prevent mold and improve resin production.
VPD (Vapor Pressure Deficit):
Optimized at 1.40, promoting efficient nutrient uptake and transpiration.
Light Intensity:
Increased to 720 PPFD at the canopy. This adjustment aims to maximize bud development and resin production during this critical flowering stage.
Feeding Details:
EC Input:
Nutrient strength maintained at 2.4 EC with a plan to monitor and potentially increase if plants continue to uptake aggressively.
Athena Nutrients Used:
Athena Core: 62 ml per 10 liters.
Athena Bloom: 88 ml per 10 liters.
PK Booster: 25 ml per 10 liters to enhance flowering nutrients.
Athena Stack (Silica): 15 ml per 10 liters for plant structure and stress resistance.
Cal-Mag: 55 ml per 10 liters to prevent deficiencies in coco.
Athena Cleanse: 30 ml per 10 liters for root zone health and to reduce salt buildup.
pH: Adjusted to 6.1 to optimize phosphorus (P), potassium (K), and magnesium (Mg) uptake during this stage.
Watering Schedule:
Watering 5 liters per 5-gallon fabric pot, ensuring full saturation but observing no runoff initially. Adjustments made:
Additional watering to achieve 10–15% runoff for salt management.
Monitoring coco moisture levels with the Blue Lab Pulse Meter, ensuring it stays above 50–60%.
Moisture Levels:
Pre-watering moisture: 40%, indicating the need to adjust watering frequency and ensure coco doesn’t dry out excessively.
Plant Observations:
Bud Development:
Buds are visibly bulking, with improved density and trichome production.
Plants are responding well to the nutrient regimen, showing no signs of stress or deficiencies.
Leaf Health:
Lower fan leaves are naturally fading, signaling proper nutrient uptake and utilization.
No tip burn or discoloration, confirming the EC levels are well-balanced.
Adjustments Made:
Light Intensity Increased:
Lights are now set to 720 PPFD, optimizing the energy available to plants for enhanced bud bulking and resin production.
Monitoring plants for signs of light stress or burn.
Runoff Management:
Increased watering volume to achieve proper runoff, maintaining root zone balance.
Monitoring and Testing:
Consistently checking runoff EC and pH to prevent salt buildup and nutrient lockout:
Runoff EC target: 2.2–2.6 EC.
Runoff pH target: 5.8–6.2.
Measured coco EC directly with the Blue Lab Pulse Meter to ensure sufficient nutrient levels throughout the day.
Next Steps for Week 7:
Gradually Increase Light Intensity:
If plants respond well, consider increasing light to 750–800 PPFD to further enhance bud development.
Evaluate Nutrient Uptake:
If coco EC drops significantly below 1.5 EC by the end of the day, consider increasing input EC slightly to 2.5–2.6.
Continue with Athena Cleanse:
Use at every watering to maintain a clean root zone and prevent salt accumulation.
Prepare for Late Flowering:
Monitor trichome development closely to plan the flush schedule.
Summary of Week 6:
Focus: Bud bulking, resin production, and maintaining optimal conditions.
Successes: Plants are thriving with healthy foliage, stable nutrient uptake, and excellent bud development.
Adjustments: Light intensity increased to 720 PPFD, ensured proper runoff, optimized moisture levels, and pH adjusted to suit mid-to-late flowering nutrient needs.
