## Likely causes, most likely first

### Pump, timer, air or emitter failure in a hydro, aero or drip system (Possible)

- Kind: Root zone; urgency: Act now
- Fix: Restore flow or air immediately: check power, timer, float switches, filters and nozzles. Mist exposed roots by hand or lower plants into solution while you fix it. In HPA and NFT, fit an alarm and a backup pump; roots die fast when misting or flow stops.
- Recovery: Plants regain turgor within hours if roots were not dead; brown, collapsed roots mean rot risk next.
- Confirm: Check pumps, timers, nozzles and drippers: Watch one full cycle: the pump starts on time, every nozzle mists or every dripper delivers, NFT channels have flow end to end, air stones bubble. Clear clogged emitters and filters. In HPA, a failed pump or blocked nozzle can kill exposed roots fast, so check this first when plants on one system wilt together.
