Critical — East A May-8 commitment NEVER implemented, substrate EC bled out, then sensors went silent
East A (12403) had 8 days of substrate data this window before sensors dropped on 06-15. Over those 8 days: feed EC averaged 1.11 mS (target 2.3–2.6+), substrate pore EC declined 3.22 → 1.73 mS (-46%), drain EC fell 4.47 → 1.97 mS. This is the room that was already on a FAIL flag from June 9 — the data confirms the recipe was never changed and the substrate is now below the coco maintenance floor. After 06-15 the substrate sensor stack goes silent (climate sensors still reporting) which means we can't see what happened in the back half of the window. Two actions: (1) raise feed EC in East A to ≥ 2.6 mS today, (2) confirm whether substrate sensors were pulled or dropped off the mesh.
Positive — West B substrate EC doubled, May-8 recipe working as intended
West B (12406) substrate pore EC climbed from 2.19 → 4.62 mS across the full 14 days, drain EC tracked 2.23 → 5.58 mS, drip steady at 2.4-2.6. That's a textbook bulking EC stack. The substrate-steering side of West B is doing what it should. The remaining problem is climate: VPD 0.93 mean (target 1.2–1.4), air temp 71.7°F, RH 65% — the canopy is still running too cool for a bulking room.
Positive — West A is the cleanest steering signature in the facility
West A (16868) ran 14 full days of 77.7% peak / 57.7% trough → 20 pp absolute dryback (lower edge of 25-35 pp ripening band), feed EC 3.00 mS holding, drain EC building 6.54 → 7.67 mS, substrate EC 4.55 → 5.58 mS. Drain−drip spread is +4.0 mS. Don't touch the recipe. For a deeper P3 in the final week, step ASI DOWN one notch (GEN 3 → GEN 2 = the MORE aggressive direction).
Watch — R/D climate runs vegetative, substrate signal is moving but light
R/D (12409) VPD 0.71, RH 77%, CO₂ 934 ppm, dryback 10.7 pp average — vegetative signature, not mid-flower. Substrate EC climbing 2.7 → 3.06 mS. Either a deliberate veg/early-flower pilot or an HVAC limit; flagging for Michael to confirm intent.

CRITICAL — substrate EC bled out, sensors offline 06-15 · Substrate sensors live 06-08 → 06-15, then went silent · substrate coverage 57% (8/14d)
THIS IS THE FAIL. East A had substrate data for 06-08 through 06-15. Over those 8 days: feed EC averaged 1.11 mS (target 2.3–2.6+), substrate pore EC FELL from 3.22 → 1.73 mS (-46%), drain EC fell 4.47 → 1.97 mS. The May-8 commitment was NOT implemented in this room and substrate is bleeding salts exactly as predicted at the June 9 audit. Then on 06-15-16 the substrate sensors went silent — climate sensors still report, soil_moist/pore_ec/drip/drain all blank. Need to know from Michael: (a) why feed EC was never raised in East A, and (b) whether sensors were pulled deliberately or dropped off the mesh.
West B substrate EC has DOUBLED over the window — 2.19 → 4.62 mS (+110%). Drain EC tracks 2.23 → 5.58 mS, drip steady at 2.4-2.6 mS. The May-8 recipe change is doing exactly what it should: the substrate is stacking. Steering side is correct. Climate side still drags — VPD averaged 0.93 kPa (bulking target 1.2-1.4), air temp 71.7°F, RH 65%. Cool canopy. Substrate is doing its job in spite of the climate, not because of it.
R/D runs a vegetative climate (VPD 0.71 mean, RH 77%, CO₂ 934 ppm, dryback only 10.7 pp). Substrate EC climbing 2.7 → 3.06 mS. Either intended veg/early-flower pilot or a recipe choice; flagging as open question for Michael.
East B substrate sensors went live on 06-18 — only 4 days of substrate data, but those 4 days show the May-8 feed-EC commitment IS in force on this room. Feed EC ramps from 1.18 → 2.89 mS, drain EC follows from 1.85 → 3.46 mS (drain > drip, healthy stacking). Pore EC substrate steady at 2.6 mS. As the room hits full production the dryback signature deepens from 1 pp → 21 pp daily — that's the room coming into a normal flower irrigation cadence.
West A is steady-state ripening: VWC peak 77.7%, trough 57.7%, ~20 pp absolute dryback every day, drain EC climbing 6.54 → 7.67 mS against a 3.0 mS feed — that's a +4.6 mS substrate stack and growing. Substrate EC trajectory 4.55 → 5.58 mS over the window — concentrating for finish. Don't touch the recipe; if you want a deeper P3 in the last week, step ASI DOWN one notch (GEN 3 → GEN 2, the MORE aggressive direction).
Raise East A (12403) feed EC to ≥ 2.6 mS today — the May-8 commitment is still not implemented and substrate is below the coco floor.
8 days of substrate data this window confirm the original FAIL: feed 1.11 mS, substrate EC 3.22 → 1.73 mS (-46%), drain EC 4.47 → 1.97 mS. Don't wait for the sensors to come back; raise feed in the recipe now. Expected effect: drain EC stabilizes within 48h, substrate EC stops bleeding.
GrowerCRIT
Walk East A and verify substrate sensor status — pulled, retired, or off-mesh?
soil_moist / pore_ec / drip / drain all went silent for East A on 06-15. Climate sensors still report normally. Either TEROS-12 nodes were physically pulled (room flipped or torn down), or the substrate node dropped off the Wirepas mesh. Re-pair if it's a mesh issue.
GrowerWARN
Drop West-side dehumidifier RH setpoint 5-8 points during lights-on to close the bulking VPD gap.
West B VPD 0.93 mean, West A 0.95, target 1.2–1.4. Air temp 70-72°F is cool, RH 62-65% is mid. Pulling RH setpoint to 58-60% during lights-on should lift VPD into 1.1+ band. Watch substrate VWC next morning — if dryback deepens, plants were transpiration-limited (good sign).
GrowerWARN
Leave West A (16868) recipe alone — for a deeper P3 in the final week step ASI DOWN (GEN 3 → GEN 2), not up.
West A is the cleanest steering signature in the facility — 20 pp dryback every day, drain EC building, substrate EC concentrating into finish. Don't chase the VPD 0.95 reading. If a deeper finish is wanted, step ASI DOWN one notch — that's the MORE aggressive direction (GEN 1 = deepest, GEN 5 = neutral).
ProcessWARN
Confirm phase intent for R/D Flower (12409) with Michael.
VPD 0.71, RH 77%, CO₂ 934 ppm, dryback 10.7 pp — climate and substrate read vegetative/early flower, not mid-flower. Document whether this room is running a propagation cycle deliberately, or whether the irrigation recipe is over-watering for a flower phase.
ProcessINFO
Document customer-stated targets per room before the next audit.
Practitioner ranges are what we grade against today because explicit Burly-stated goals (target dryback %, substrate EC ceiling, VPD per phase) aren't in the file. Capture Michael's intended values per room — even one sentence each — so the next audit grades deviation from goal, not deviation from textbook.
ProcessINFO
Confirm AUTOMAIT enablement status.
AUTOMAIT was purchased but not enabled at the May 8 audit. Worth a short check-in: West A is the clean candidate for a single-room AUTOMAIT pilot if Michael wants to start. If already enabled, pull AUTOMAIT config and compare actual irrigation events to guardrails before the next audit.
5 · Open Questions
Why was East A (12403) feed EC never raised? — Recipe change committed May 8, never executed. Need to know if it's a recipe deployment issue, a controller mismatch, or a Michael decision.
East A substrate sensors — pulled, retired, or off-mesh? — Substrate stack silent since 06-15. Climate still reports. Walk the room.
R/D (12409) phase intent. — Vegetative climate signature; is this a deliberate prop/veg pilot or a recipe error?
Customer-stated targets per room. — Burly has not documented intended dryback %, EC ceiling, or VPD by phase. Capture even a one-line goal per room.
AUTOMAIT enablement. — Status as of 2026-06-23 unknown; was parked at May 8.
West-side HVAC — setpoint or capacity? — VPD gap is closing but slowly. Setpoint fix is easy; capacity limit is a hardware conversation.

Daily peak/trough/mean aggregates computed from the raw point stream (no SDK clamping).
Prior 6-week (2026-04-01 → 2026-05-13) and 2-week (2026-05-26 → 2026-06-09) audits used to grade prior commitments.

Methodology
Dryback is absolute percentage points (peak − trough VWC), not relative to field capacity.
Phase targets are practitioner ranges from AROYA's Crop Steering Guide, Grodan Cannabis Ed. Ch. 3–4, Athena, and Growlink — surfaced as benchmarks, not as customer goals.
EC stack is drain − drip EC. Positive means substrate concentrating salts (stacking). Negative means leaching.
ASI direction — GEN 1 = deepest dryback, GEN 5 = neutral, VEG 6-10 = vegetative. For more aggressive steering, step DOWN toward GEN 1.
AROYA = sensors + analytics. Controls integration via partners (Argus, Priva, Growlink). AUTOMAIT (all caps) is AROYA's autonomous irrigation engine.
Data quality flags
East A (12403): substrate sensor stack stopped reporting 06-15. Climate sensors normal through 06-22.
East B (12404): substrate sensor stack came online 06-18 — only 4 days of substrate data.
