Sticky Broccoli Auto — Week 3 Update
Grower: Stoney Stark / Little Lilly Farms
Event: Eternity Cup
Stage: Late Veg (Pre-Flower Transition Approaching)
⸻
Growth Overview
Week 3 showed aggressive vegetative expansion. Plants are stacking nodes quickly with strong lateral branching and tight internodal spacing. No visible pistils yet, but structure suggests pre-flower is approaching soon.
Feeding frequency has increased to near-daily, which aligns with rapid coco dry-back under elevated PPFD and warmer temps. Plants are handling higher EC without tip burn or clawing, indicating strong uptake and healthy root function.

Light Settings
2/5 — Spectrum Adjustment
• 60% Cool
• 40% Warm
• 0% IR
• 0% UV
• 430 PPFD
This spectrum favors vegetative growth by emphasizing blue light for tighter structure while maintaining enough red for balanced development.
⸻
Environment
2/6
• Temp: 84°F
• RH: 69%
VPD is on the higher transpiration side at that temperature. This explains the heavier feeding demand and strong nutrient pull. Plants are metabolically active and drinking accordingly.
⸻
Watering & Nutrient Log
All nutrient amounts listed per gallon.
⸻
2/6
• 1 gallon mixed
• ¼ gallon per plant via auto system
• 1050 PPM
• 5.8 pH
.5 ml Silicium
2 ml Mag-Cal
10 ml Cocos A
6 ml Cocos B
1 ml Royal Rush
4 ml Pure Zym
4 ml Photo +
2 ml Fish Sh!t
5 ml Ruby Fulvic
Notes: Elevated PPM largely from Scientetics Mag-Cal addition. No signs of toxicity; plants appear to be responding positively.
⸻
2/7
• Light defoliation
• Cleaned lower growth to prevent sprayer interference
• Removed 2 larger fan leaves per plant for penetration
• 5-gallon batch mixed
• Auto system ran 2 minutes
• 5.8 pH
• No runoff
Nutrient mix remained identical.
⸻
2/8
• Auto system ran 3 minutes
• Small runoff achieved
• 1250 PPM
• 5.8 pH
Same nutrient ratios maintained.
Observation: 1250 PPM in week 3 is aggressive for autos, but structure and leaf posture suggest they’re metabolizing efficiently.
⸻
2/10
• Removed 2 large top leaves per plant to open side branching
• 2 gallons mixed
• Auto ran 3 minutes
• ½ gallon per plant
• Small runoff achieved
• 900 PPM
• 5.8 pH
Adjusted mix:
.5 ml Silicium
2 ml Mag-Cal
10 ml Cocos A
6 ml Cocos B
1 ml Royal Rush
4 ml Pure Zym
2 ml Fish Sh!t
5 ml Ruby Fulvic
Photo + removed this feed cycle.
Lowered PPM to 900 — a smart reset to prevent salt stacking while maintaining daily feeding cadence.

Nutrient Function Breakdown
Silicium
• Strengthens cell walls
• Improves stress tolerance
• Supports upright leaf posture
Mag-Cal
• Provides calcium for cell structure
• Magnesium for chlorophyll production
• Essential under high LED intensity
Cocos A & B
• Primary macro base (NPK + micros)
• Drives vegetative expansion
Royal Rush
• Early metabolic stimulator
• Supports nitrogen utilization
Pure Zym
• Enzyme product
• Breaks down dead root matter
• Prevents medium compaction in coco
Fish Sh!t
• Microbial inoculant
• Enhances nutrient conversion
Ruby Fulvic
• Chelation support
• Improves micronutrient uptake
• Increases efficiency at higher EC
Photo + (earlier feeds)
• Carbohydrate support
• Microbial fuel
• Supplemental metabolic enhancer
⸻
Technical Observations
• Feeding frequency is appropriate for 84°F + 430 PPFD
• Achieving slight runoff on 3-minute cycle is ideal
• Dropping from 1250 to 900 PPM was a strong preventative move
• No pistils yet — expect pre-flower within 5–10 days
At this pace, they are setting up for a strong stretch phase. Structurally, they look primed for a controlled but productive transition into flower.
