This week marks the true beginning of flowering, as all plants are now showing clearly visible pistils at the nodes and an active, uniform stretch. The transition to 12/12 has been fully assimilated, and the crop is responding with strong, healthy growth.
The canopy is very well leveled, with an open structure thanks to the previous LST/SCROG work. Tops are correctly oriented toward the light, showing no signs of stress, and light penetration remains good even in the mid-canopy.
From an environmental standpoint, conditions have remained very stable throughout the week:
Average temperatures around 24–25 °C
Relative humidity between 55–62%
VPD consistently in the 1.1–1.3 kPa range
This results in optimal transpiration and highly efficient nutrient uptake.
Lighting has been progressively adjusted to reach 700–720 µmol/m²/s PPFD, which is ideal for early flowering, with stable ambient CO₂ levels (~700 ppm). No signs of light stress or photoinhibition have been observed.
Regarding nutrition, irrigations have been maintained around EC ~1.1–1.2 mS and pH 6.3, combining BioGrow, BioBloom, enzymes, and stimulators. The plants display a healthy green color, with no deficiencies or excesses, and show a very positive response after each feeding.
Overall, this has been a key and very well-executed week, laying a strong foundation for the upcoming bulking phase. The crop enters Flowering Week 2 with strength, balance, and excellent yield potential.
