1 entriesFrequently asked
- Why are my hydroponic plant leaves turning yellow?
- Most often a nitrogen deficiency or a pH outside 5.5–6.5 that locks nutrients out. Check pH and EC first, then compare the pattern of yellowing with the deficiency pages.
- How do I fix root rot in hydroponics?
- Roots that are brown, slimy and smell bad point to root rot. Raise dissolved oxygen, keep the reservoir cool, and remove dead roots; the root rot page gives the full procedure.
- Can I diagnose a plant problem from a photo?
- Yes. The AI plant diagnosis tool reads a photo or a description and returns a likely cause with a treatment plan.
