Sticky Broccoli Auto â 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 â 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
⢠Ÿ 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 theyâre 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 â 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 â expect pre-flower within 5â10 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.
