Grow Diary Stardawg

Week #7 (Mid-Flower – Week 2)

This week marked the second week of mid-flower but also brought a major shift in the grow. Up until this point, I had two Stardawg plants; however, at the end of Week 6, one went full herm - showing pollen sacs and male flowers throughout the lower and mid nodes. The other plants showed no signs of stress or hermaphroditism at this stage. I made the difficult but necessary decision to remove the affected plant. As a result, I entered Week 7 with three plants remaining: two Blueberry and one Stardawg.

Stardawg finished her stretch within two weeks of pistil emergence, reaching a final height of 36". For those interested in stretch behavior: on the day I flipped the light schedule from 18/6 to 12/12, Stardawg stood at 11" tall. This gives a height multiplier of approximately 3.27x from flip to peak height - under intense light and after topping four days prior to the light change.

Nutrient demands increased significantly during mid-flower. I fed mid-flower nutrients at 1,000–1,100 ppm three times throughout the week to keep pace with the plant’s needs. Runoff was monitored closely and remained in the target range of 1,200–1,400 ppm, with a consistent runoff pH of 6.2 and input pH around 6.6. Daily watering continued at 4 liters per day with Cal-Mag support.

Environmental conditions remained stable: daytime temps held at 82°F, nights at 72°F, RH averaged 50%, and soil temperature hovered around 75°F. The light was held steady at 15" above the canopy, delivering an average PPFD of 850 and a DLI of 37. Mid-week, UV-A exposure reached its peak for the cycle - 2 hours per day - where it will stay until late flower.

Since I avoid defoliation past Week 3 of flower, all structural pruning was completed by the start of mid-flower. In Week 7, aroma began to intensify, and while still developing, Stardawg was producing a rich, complex scent - sweet, spicy, earthy, and reminiscent of walking into a coffee house filled with the smell of freshly brewed drinks.
