Troubleshooting guide
People search this when the grow is already at risk. Use this page to make one clean diagnosis, then save the crop and setup so the next check is scheduled instead of guessed.
Diagnosis tool
Work through these in order. Beginners lose crops when they change every variable at once.
| Check | What to look for | If it fails |
|---|---|---|
| Roots | Pale color, firm texture, no bad smell | Clean, improve oxygen, or restart backups. |
| Light | Compact growth without burned tips | Adjust distance gradually, not all at once. |
| Water | No algae, smell, or heat stress | Block light and clean between cycles. |
| Numbers | Crop range near pH 5.8-6.2, EC 0.8-1.4 | Adjust slowly after roots and water are checked. |
| Cause | Why it matters | Beginner action |
|---|---|---|
| too many charts | This is the most common first variable to confirm. | Pick the crop range first. |
| untrusted meters | This can compound the original issue if ignored. | Measure after mixing. |
| daily overcorrection | This can compound the original issue if ignored. | Record changes weekly. |
| mixing nutrients too strong | This can compound the original issue if ignored. | Adjust slowly. |
| not recording changes | This can compound the original issue if ignored. | Use crop symptoms to decide whether numbers matter. |
Start a backup lettuce cycle while you diagnose the current grow. A backup crop protects momentum and gives you a clean comparison if the damaged crop does not recover.
Buy the setup review when you are not sure whether the issue is crop choice, system mismatch, lighting, or nutrient management. The review is designed to turn messy beginner context into one next action.
Use a safe range, then watch the plant before chasing perfect numbers.
Not immediately. Check roots, water condition, light, and crop stage first so you do not create a second problem while fixing the first.
Restart backup seeds when seedlings collapse, roots smell rotten, or the crop has been stalled for more than a week with no clear improvement.
