Day 16: Recovery is holding · Autoflower Cannabis in a LetPot: Air Gap and Droop Recovery

Visual evidence

What Dud2Bud observed

Current growth is moving in a healthier direction. The remaining damaged leaves are mostly older tissue, while the newest canopy shows no clear active spread of burn or curl. Stability is safer than another reservoir change.

The upper canopy has expanded since the previous photo.

New central leaves are green and opening more normally.

The newest growth is not showing the same tight curl seen during the earlier stress peak.

The plant remains upright.

Several older lower leaves are yellowing, brown, or necrotic.

Some outer leaves still hang downward.

The reservoir strength, waterline, roots, and EC are not visible.

Old damage

Brown and yellow lower leaves that were already damaged during the earlier nutrient-strength episode.

Old damage

Existing brown tips and margins that are not extending into the newest leaves.

Still uncertain

The close framing makes exact comparison of posture difficult.

Still uncertain

Some leaf discoloration may be affected by lighting and image angle.

Still uncertain

No user-confirmed recent change is available for this check-in.

Still uncertain

Root condition and air gap remain unseen.

Dud2Bud decision

Protect the recovering new growth

The plant is improving without a new correction, so keeping the quarter-strength reservoir stable is more useful than reacting to old damaged leaves.

What to do

Keep the quarter-strength reservoir steady

Make no new nutrient or water change today. The newest growth is improving, so leave the current solution and root-zone level alone while the plant sheds its older damage.

1 Leave the reservoir and waterline unchanged.
2 Do not add more nutrients based on the appearance of old leaves.
3 Judge progress by new leaves, not by tissue that is already brown or necrotic.

Exact change

none

Keep steady

Keep the reservoir at the current quarter-strength mix, maintain the same waterline and air gap, and avoid adding supplements or extra A/B.

What happened before the next photo

Topped up with 1/2 strength solution.

Full assessment

How this photo was assessed

The report separates visible facts, possible explanations and the final care decision so uncertainty remains visible.

Visible evidence What was visible in the photo

Vigor

Improving

Vigor is recovering in the active growth, although the plant is still shedding or losing older damaged foliage.

Confidence: 80%

Color Analysis

Improving

The reduced-strength reservoir appears more suitable than the earlier stronger mix, though exact nutrition cannot be confirmed visually.

Confidence: 78%

Growth Development

Improving

Vegetative development is continuing and current growth quality has improved.

Confidence: 86%

Progress Comparison

Improving

The trajectory is positive when judged by new growth; old tissue is lagging behind and should not drive a new treatment.

Confidence: 87%

Damage Classification

Improving

The stress pattern is becoming residual rather than actively spreading.

Confidence: 82%

Distribution Analysis

Improving

The plant is recovering from a past whole-plant stress rather than developing a new canopy-wide problem.

Confidence: 83%

Possible mechanisms What could explain it

Disease

Watch

Root disease cannot be ruled out, but improving new growth makes immediate disease treatment inappropriate.

Confidence: 50%

Nutrition

Improving

The earlier nutrient-strength stress appears to be easing. Adding nutrients now could reverse that progress.

Confidence: 72%

Environment

Watch

Environmental conditions may influence final recovery, but changing them now would add unnecessary uncertainty.

Confidence: 55%

Biotic Damage

Clear

Pests are not supported as the leading explanation.

Confidence: 78%

Water Relations

Watch

Root-zone water and oxygen balance should remain steady and monitored, but there is no current visual reason to change it.

Confidence: 52%

Structural Analysis

Improving

Structure is adequate for recovery. Pruning or support changes are not needed based on this image alone.

Confidence: 70%

Decision checks Why this action was chosen

Recovery

Improving

Recovery is now the dominant story, judged by current growth rather than old leaves.

Confidence: 88%

Information Gap

Watch

More evidence could refine confidence but would not change today's action.

Confidence: 68%

Limiting Factor

Watch

The current limitation is more likely recovery from prior root or nutrient stress than an urgent new factor.

Confidence: 58%

Confidence Audit

Improving

Confidence is high enough to stop active intervention and continue recovery monitoring, but not yet to call the plant fully recovered.

Confidence: 85%

Intervention Evaluation

Improving

The prior nutrient-strength correction appears helpful enough to continue holding conditions steady.

Confidence: 83%
