Germination & Emergence
1/15 ā Planting Day
Seeds were sown directly into pre-moistened coco. Each pot was primed with ¼ gallon of low-EC nutrient solution to hydrate the medium and establish beneficial biology without stressing seedlings.
1/16 ā Moisture Maintenance
⢠Mixed ½ gallon RO
⢠Applied 250 ml per plant to lightly moisten the top layer
⢠pH: 5.8
⢠PPM: ~90
Additives (per gallon):
⢠5 ml Ruby Fulvic
⢠5 ml Photo+
This was a very light biological watering focused on chelation, root signaling, and photosynthetic support.
1/19 ā Full Emergence
All four Sticky Broccoli Auto plants successfully emerged. Light intensity was increased to ~150 PPFD and the light schedule was set to 20/4.
Each plant received 250 ml of nutrient solution.
⢠pH: 5.8
⢠PPM: ~275
Nutrients (per gallon):
⢠0.5 ml Silicium
⢠2 ml Coco A
⢠2 ml Coco B
⢠2 ml Power Roots
⢠2 ml Pure Zym
⢠5 ml Ruby Fulvic
⢠1 ml Fish Sh!t
āø»
Nutrient Purpose (Early Stage)
⢠Silicium: Strengthens cell walls and improves early stress tolerance
⢠Coco A & B: Provides balanced macro and micronutrients tailored for coco
⢠Power Roots: Encourages rapid root initiation and lateral root development
⢠Pure Zym: Enzymes keep the rhizosphere clean and improve nutrient availability
⢠Ruby Fulvic: Enhances nutrient chelation and uptake at very low EC
⢠Fish Sh!t: Introduces beneficial microbes for nutrient cycling and root health
āø»
Notes & Outlook
Germination was fast and uniform across all four plants with no signs of stress. The low-EC, biology-focused approach is working as intended, establishing a healthy root zone before pushing nutrition. Plants will remain on gentle feeds while roots expand and seedlings transition into early vegetative growth.
Next focus: steady PPFD increases, daily moisture control, and continued root development.

Grow Technique Note ā Tall Fabric Pots & Autoflowers
Using taller fabric pots provides several advantages for autoflower cultivars, especially during early root development:
⢠Improved root depth: Autos tend to send a dominant taproot early; extra vertical space allows uninterrupted downward growth
⢠Better oxygenation: Taller profiles increase air exchange through the sidewalls, reducing the chance of anaerobic zones
⢠More efficient nutrient uptake: A deeper root column improves access to moisture and nutrients, especially in coco
⢠Reduced early stress: Strong early root architecture helps autos handle later increases in PPFD and EC without stalling
⢠Improved water distribution: Gravity-assisted flow encourages roots to chase moisture downward rather than circling
This setup supports faster early establishment, which is critical for maximizing autoflower yield within a fixed lifecycle.

Stoney_Stark Stoney_Stark Week 2 Update ā Sticky Broccoli Auto
Grower: Stoney Stark / Little Lilly Farms
Stage: Early Veg (Week 2)
āø»
Growth Overview
Plants are establishing well and responding positively to automation. No visible stress from the siphoning incident. What initially appeared to be a nitrogen deficiency was later identified as a magnesium deficiency common in coco systems, with a light green fade also indicating the early onset of nitrogen demand.
āø»
Irrigation & Automation
⢠Transitioned to auto-irrigation emitters this week
⢠Distribution appears even across all plants
⢠Initial siphoning issue identified and corrected by removing pump after feed cycle
⢠Monitoring pot weight closely to avoid overwatering
āø»
Watering & Feeding Log
1/29 ā First Auto-Irrigation Run
⢠Amount: ~¼ gallon per plant
⢠PPM: 420
⢠pH: 5.9
Nutrients (per gallon):
⢠0.5 ml Silicium
⢠4 ml Cocos A
⢠4 ml Cocos B
⢠2 ml Power Roots
⢠3 ml Pure Zym
⢠5 ml Ruby Fulvic
⢠2 ml Photo+
⢠1 ml Fish Sh!t
Notes: First run with emitters. Feed appeared evenly distributed.
āø»
1/31 ā Siphoning Incident
⢠Issue: 5-gallon bucket siphoned into all 4 plants
⢠Result: No negative plant response observed
Nutrients (per gallon):
⢠0.5 ml Silicium
⢠4 ml Cocos A
⢠4 ml Cocos B
⢠2 ml Power Roots
⢠3 ml Pure Zym
⢠5 ml Ruby Fulvic
⢠2 ml Photo+
⢠1 ml Fish Sh!t
āø»
2/1 ā Auto-Irrigation Dialed In
⢠Feed Time: 1 minute
⢠Runoff: Small amount
⢠Adjustment: Pump removed immediately after feed to prevent siphoning
Observations:
⢠Noticed early light green coloration initially interpreted as nitrogen deficiency
⢠Adjustments made to increase available nitrogen
Nutrients (per gallon):
⢠0.5 ml Silicium
⢠4 ml Cocos A
⢠4 ml Cocos B
⢠2 ml Power Roots
⢠3 ml Pure Zym
⢠5 ml Ruby Fulvic
⢠2 ml Photo+
⢠1 ml Fish Sh!t
⢠+2 ml additional Cocos A
⢠+1 ml Royal Rush
āø»
2/2 ā Moisture Hold
⢠Pots felt heavy
⢠Decision made to skip watering for 1ā2 days to avoid overwatering
āø»
2/3 ā Light Auto Feed + Deficiency Diagnosis
⢠Feed Time: 1 minute
⢠Pots: Still holding moisture; irrigation paused for the next couple days
Updated Diagnosis:
⢠What initially appeared to be nitrogen deficiency was confirmed to be magnesium deficiency, common in coco when running low-mineral water
⢠The light green coloration also indicates the beginning stages of increased nitrogen demand
Correction Plan:
⢠Adding Scientetics MagCal at 2 ml per gallon starting next feed to supply readily available magnesium and calcium
⢠Nitrogen levels maintained via Cocos A and Royal Rush without over-increasing EC
Nutrients (per gallon):
⢠0.5 ml Silicium
⢠6 ml Cocos A
⢠6 ml Cocos B
⢠3 ml Power Roots
⢠4 ml Pure Zym
⢠4 ml Photo+
⢠2 ml Fish Sh!t
⢠1 ml Royal Rush
⢠(MagCal to be added next feed)
āø»
Issues & Adjustments
⢠Magnesium deficiency: Identified and corrected with planned MagCal supplementation
⢠Early nitrogen demand: Being met through controlled increases to Cocos A and Royal Rush
⢠Overwatering risk: Managed via pot-weight monitoring and irrigation pauses
⢠Auto-irrigation: Functioning correctly after siphon fix
āāā
Deficiency Learning Note
This week provided a useful reminder about how nutrient deficiencies present in coco-based systems. What initially appeared to be early nitrogen deficiency was identified as magnesium deficiency, which commonly manifests as a light green fade and interveinal chlorosis on lower leaves. In coco, magnesium can become limiting even when using coco-specific base nutrients, particularly when running low-mineral or RO water.
The light green coloration also coincided with increasing nitrogen demand as the plants transitioned deeper into vegetative growth. Rather than aggressively raising EC, the correction strategy focused on restoring magnesium availability while maintaining balanced nitrogen levels.
āø»
Plan for Week 3
⢠Introduce Scientetics MagCal at 2 ml/gal
⢠Allow pots to dry slightly before next irrigation
⢠Monitor color correction in new growth
⢠Fine-tune auto-irrigation timing and volume
⢠Gradually increase feed strength as plants size up
