EVD420 Stage
Report starts from end of Week 1 / beginning of Week 2 after planting.
All plants are connected to a shared irrigation system (recent pH instability corrected to ~5.5).
⸻
Deep Forest
* Shows the strongest growth rate in the group
* Large, healthy leaves
* Slight substrate limitation (not enough coco during transplant)
* Possible future transplant if timing allows before flowering
* Light defoliation applied to improve light penetration (super-auto, expected to recover well)
⸻
PermZ
* Stunted growth, remains at seedling stage
* Minimal activity observed
* Last seed — plant will be kept and monitored, not discarded
* High interest in preserving genetics
⸻
Sour Puffs
* Also slow / stalled development
* Observation continues for ~1 more week
* Low priority due to available backup seeds
⸻
Tokyo Buth
* Healthy development
* Second node already formed
* No training yet — allowing further vegetative growth
⸻
Black Mamba 42
* Affected by earlier low pH issue (minor burn, leaf twisting)
* System now stabilized (pH ~5.5)
* Plant continues stable, mid-range growth despite stress
⸻
DC Kush
* Similar minor pH stress symptoms on lower leaves
* New growth appears healthy and stable
* Shows consistent, average growth rate
⸻
Snake Hypnosis
* Stable growth
* Dark, saturated leaf color
* No intervention — currently observing
⸻
Skywalker Haze
* Strong, healthy growth
* Good response to nutrients
* Light green, vigorous foliage
* No training yet
⸻
Hippo High
* Slight leaf curling (same pH issue)
* System stabilized → expected recovery
* Growth remains normal
⸻
Ice Cream Zoap
* Recently rooted and adapted to hydro system
* Planted ~5 days later than others → naturally behind
* Placed in separate hydro setup (dedicated box)
* Running light nutrient solution to build root mass
* High-priority strain for full-cycle evaluation
⸻
Notes
* All plants were affected to some degree by early pH instability, now corrected
* Current phase: stabilization + observation
* No aggressive training yet (except selective defoliation

EVD420 Week Context
This week was defined by system instability:
* Drip irrigation system malfunctioned
* Hydro system temporarily failed
* New pH meter was defective → caused pH fluctuations
* Result: multiple plants experienced nutrient burn and stress
System is now:
* stabilized
* pH corrected
* irrigation restored
All plants received light feeding (FishForce ~10 ml/L) where applicable.
⸻
Major Change
* Ice Cream Zoap failed (did not adapt to hydro, likely due to pH instability) → removed
* Deep Forest transplanted to hydro system (replaced it)
⸻
Deep Forest
* Transplanted from coco → hydro (stress expected)
* Strong root system, handled transplant relatively well
* Remains most vigorous plant
* Now has access to more space and nutrients
⸻
Hippo High
* Handles stress well
* Light training + defoliation applied
* Stable condition
⸻
DC Kush
* One of the least affected
* Maintains healthy structure
* Stable growth
⸻
PermZ
* Finally resumed growth, but still weak and unstable
* Irregular leaf formation → possible mutation / stress response
⸻
Snake Hypnosis
* Slow growth, heavily stressed
* Twisted leaves
* Some recovery visible
⸻
Skywalker Haze
* Strong growth
* Responded well after correction
* Light defoliation + structure work applied
⸻
Tokyo Buth
* Growth improved
* Among the most stable performers under stress
⸻
Sour Puffs
* Previously stalled, now showing recovery
* Still behind others, but improving
⸻
Black Mamba 42
* Very solid recovery
* Burnt leaves removed
* Good structure and vigor
⸻
General Actions
* Light training applied across all plants
* Removal of:
* burnt leaves
* damaged foliage
Current Strategy
* Maintain stable pH
* Keep light nutrient solution
* Focus on recovery and stabilization
