Afghan Kush
Afghan Kush • Late Flower Day 51 (Week 8 Day 2)
May 22, 2026
AI Observation from 2026-05-22: Late Flower Day 51 • Week 8 Day 2 Recent

82% confidence Heavy finish — dense frosty colas across canopy; monitoring environmental stress and nutrient runoff

Cautions: No peroxide recommendation is made due to prior oxidizer/ClO2 chemistry history in grow_notes • Refer to company SOPs for IPM
Summary
  • ✅ Heavy finish FD51 Dense, frosty colas across canopy; bud stack remains strong despite prior stress history
    Why?
    Afghan Kush shows significant resin production and floral density consistent with late-stage maturation.
  • ⚠️ Ongoing bleaching White cola tips and hooked sugar leaves persist at PPFD 1200
    Why?
    Persistent high light intensity (PPFD 1200) at 80% LED is exceeding the current light saturation point for these tops.
  • ⚠️ Chlorosis persists Older fans show interveinal yellowing and brown margins; runoff EC 3.20–3.57
    Why?
    Pore EC 1.85–2.73 and elevated runoff suggests nutrient accumulation in the substrate.
  • 🟠 Dense cola risk Large colas with night RH 56.5% and VPD 0.844; monitor for botrytis
    Why?
    High humidity and low VPD during night cycle increase the risk of interior mold in large-format buds.

Actions Now
  • HIGH Consider easing light stress for 48h
    Details
    Category: Environment
    Why: Aim canopy PPFD 1050–1150 and explore reducing UC from 90% to 70–80%.
  • HIGH Hold current feed near EC 2.5
    Details
    Category: Nutrition
    Why: Verify Part A/C pump output and dripper EC/pH before recipe changes.
  • MEDIUM Tighten feed distribution
    Details
    Category: Irrigation
    Why: Avoid >90 min daytime gaps and keep intershot dryback near ≤2 VWC.
  • MEDIUM Target late-flower humidity tighter
    Details
    Category: Environment
    Why: Day RH 50–55%, night VPD about 0.95–1.10 if HVAC allows.
Watchouts (72h)
  • Expansion of white cola tips after reducing PPFD/UC intensity
  • New necrotic margins on upper or mid-canopy leaves
  • Any dense cola interior browning, gray growth, or sour odor
  • Substrate sensor gaps over 90 min or repeated intershot drybacks above 2 VWC
Prevention (next run)
Mid Flower
  • Verify pump output for Part A/C during stretch/mid flower
Late Flower
  • Cap late-flower PPFD below bleaching threshold for Afghan Kush
  • Limit UC intensity ramp for this cultivar
  • Schedule dense-cola interior checks from Week 7
Suggested Targets
  • EC: ~2.5 mS/cm (maintenance)
  • pH: 5.94–6.14 (runoff range)
  • Day Humidity: 50–55% RH
  • Night VPD: 0.95–1.10 kPa
  • PPFD: 1050–1150 µmol/m²/s
