Second real week of flowering completed with a very stable transition after the stretch phase. Plants have finished stretching and clear flower site formation is now visible across the canopy, with abundant white pistils and a very uniform structure.
The environment has been kept well controlled throughout the week, running temperatures around 24–25 °C, relative humidity close to 50–55%, and a stable VPD in the 1.4–1.5 kPa range. This has allowed proper transpiration without any signs of stress. Root zone temperatures remained in the optimal range, around 20–21 °C, supporting healthy root activity.
In terms of lighting, PPFD was progressively increased to around 850–880 µmol/m²/s, resulting in a DLI of approximately 38–39 mol/m²/day. This is a high but safe level for this stage, always supported by a balanced environment. Plant response has been very positive, with no signs of light stress.
Nutrition has been gradually adjusted toward flowering, maintaining a good balance between continued growth and floral development. EC has been stable around 1.1–1.2 mS/cm with a pH close to 6.3. Leaves remain healthy with good turgor and overall color, with slight tonal variations that are normal during this transition phase.
Overall, a very solid week: vigorous plants, well-formed structure, and a clean, healthy start to flower production. Everything is set up perfectly to enter week 3, where the focus will be on consolidating early bud development while maintaining environmental and root-zone balance.
