Sour Diesel - Week 1 Weekly Grow Log
Week 1 | Days from Sprout: 1-7 | Germinated: Nov 6, 2026
Week Dates: Nov 6-Nov 12, 2026 | Growth Phase: Seedling
Overall Status
Sour Diesel completed its first seven days above coco alive and upright, with slow but observable early growth. The seedling remained very small, although the first serrated true leaves emerged and expanded slightly. Leaf color was generally green. The grower described progress as underwhelming, but no failure was established.
Growth
The seed emerged November 6 (Day 1) after being planted in coco November 1. Early cotyledons were somewhat asymmetric and partly folded. By Day 4 (November 9), small true leaves were extending beyond the cotyledons. Day 5 photographs showed slight additional leaf expansion and an upright stem. On Day 6 (November 11), growth remained modest, with green foliage and no clearly confirmed second true-leaf pair. Day 7 (November 12) photographs showed the first leaves continuing to develop, but the seedling was still quite small. Approximate reported height: 1 inch.
Lighting / PPFD
The shared tent used a 20-hour-on, 4-hour-off light schedule. On November 6 the main fixture was increased from Level 6 to Level 7. Flowering canopy PPFD was approximately 700-800+ µmol/m²/s after the change; seedling-area PPFD measured about 225 µmol/m²/s outside the clear humidity cup. Light directly under the cup was not confirmed for Sour Diesel. The seedling remained under a ventilated cup during early establishment.
Feed / Root Zone
The seed was planted directly in coco November 1 after approximately 2-3 days of soaking, without a visible taproot at planting. On November 4, approximately 15 mL of RO-based nutrient solution (EC 0.65 mS/cm, pH 5.8) was applied in a ring around the planting location; the outer coco was lightly misted. On November 6, the pot remained heavy and moist, so no additional water was applied. These are documented actions, not a complete weekly irrigation total.
Environment / 7-Day Average
The supplied Main Tent AI+ weekly data screen showed average air temperature 79.1°F, relative humidity 54.7%, VPD 1.34 kPa, and water temperature 75.4°F. Recorded ranges were 71.9-87.7°F, 34.5-79.5% RH, and 0.51-2.27 kPa VPD. These are shared tent readings, not measurements inside the seedling humidity cup. Reservoir pH and EC statistics on the screen describe the shared system and should not be mistaken for the seedling root zone.
Interventions
A ventilated Solo cup with five large holes was used over the seedling during early establishment. On November 6 the grower chose not to water because the coco was still moist. The shared tent light was raised to Level 7 on November 6. The cup remained in use at least overnight during the first week; its exact removal date for Sour Diesel was not established. The seedling was monitored without aggressive corrective changes.
What the Plant Indicated
Green color, an upright stem, and gradual emergence of serrated true leaves indicate continued development. However, the plant was notably small by Day 7 and its pace lagged the grower’s expectations. The photographs alone do not establish a nutrient deficiency, root problem, or specific cause for slow growth.
Plan for Next Week
Monitor enlargement of the first true leaves and appearance of the next pair, along with stem strength and leaf color. Continue checking coco moisture before applying small amounts of nutrient solution. Avoid major changes based solely on the seedling’s small size; compare progress across several days.
Weekly Takeaway
Sour Diesel survived Week 1 and made visible, if slow, progress from emergence to small true leaves. Day 1, Day 4, and Day 7 photographs document the change. The key question for Week 2 is whether leaf development begins to accelerate.
