š± Flowering Update ā Full Week 5 Breakdown ā Entering Week 6
Week 5 was focused on entering full bulking mode with a controlled increase in volume and EC, followed by a deliberate pause to restore root oxygenation after several heavy feeds.
š§ Irrigation & Nutrition ā Week 5 (Exact Recipes)
Start of Week 5 ā 7/1 (22 L | 21 °C)
⢠EC: 1.568 mS · pH: 6.3
⢠Sensi Cal-Mag Xtra: 30 ml
⢠Bio·Grow: 6.3 ml
⢠Bio·Bloom: 109 ml
⢠TopĀ·Max: 22ā23 ml
⢠Bio·Heaven: 28 ml
⢠Bud Candy: 38 ml
⢠Atazyme: 25 ml
ā”ļø First full-volume bulking feed. Strong uptake and no lockout signs.
Mid Week 5 ā 9/1 (22 L | 21 °C)
⢠EC: 1.568 mS · pH: 6.3
⢠Sensi Cal-Mag Xtra: 30 ml
⢠Bio·Grow: 6.3 ml
⢠Bio·Bloom: 133 ml
⢠Top·Max: 23 ml
⢠Bio·Heaven: 21 ml
⢠Bud Candy: 38 ml
⢠Atazyme: 25 ml
ā”ļø BioĀ·Bloom increased to push flower mass. Plants responded with visible calyx stacking.
End of Week 5 ā PK Introduction ā 11/1 (22 L | 21 °C)
⢠EC: 1.640 mS · pH: 6.3
⢠Sensi Cal-Mag Xtra: 30 ml
⢠Bio·Grow: 6 ml
⢠Bio·Bloom: 115 ml
⢠Top·Max: 23 ml
⢠Bio·Heaven: 21 ml
⢠Bud Candy: 38 ml
⢠Atazyme: 25 ml
⢠PK 13/14: 6 ml
ā”ļø Controlled PK introduction. EC peaked safely. Minor tip burn confirmed we were at the productive upper limit.
Recovery Feed ā 13/1 (22 L | 21 °C)
⢠EC: 1.370 mS · pH: 6.2
⢠Sensi Cal-Mag Xtra: 25 ml
⢠Bio·Grow: 5 ml
⢠Bio·Bloom: 105 ml
⢠Top·Max: 22 ml
⢠Bio·Heaven: 20 ml
⢠Bud Candy: 36 ml
⢠Atazyme: 22 ml
ā”ļø Intentional reduction to let the substrate breathe after multiple heavy irrigations.
š”ļø Environmental Data (Week 5 Averages)
⢠Day: 24ā25 °C
⢠Night: 18ā19 °C
⢠Humidity: 50ā55 %
⢠VPD: ~1.0ā1.3 kPa
⢠PPFD: ~880ā920 µmol/m²/s
⢠DLI: ~39ā40 mol/day
Stable conditions allowed efficient nutrient uptake without excess transpiration.
š§ Plant Response
⢠Strong structure supporting increasing flower weight
⢠Active bulking phase (buds still stacking)
⢠Minor tip burn = intentional high-performance feeding
⢠Color differences consistent with F1 phenotype variability, not deficiencies
š Focus for Week 6
⢠Resume irrigation only when pots are clearly light
⢠Next feed: flowering base without PK
⢠Following feed: single, targeted PK 35/60 application
⢠Maintain PPFD below 920 (no COā this cycle)
⢠Preserve night temperature differential to enhance density and color expression
Week 5 set the foundation for final mass. Week 6 is about precision finishing, not pushing numbers.
