Trace a Yellow Leaf Back Through the Aquaponic System
How to investigate aquaponic nutrient problems without guessing: confirm water chemistry, crop pattern, source water, feed, solids, and lab evidence in order.

When Irrigation Signals Disagree, Check the Assumptions Before You Water
Use a short diagnostic sequence when a water budget, soil-moisture reading, rain record, or field observation points to a different irrigation decision.

Work Through a Daily Irrigation Water Budget
Use a simple daily root-zone deficit example to track depletion, record the assumptions, and correct the estimate when field measurements disagree.

Place soil-moisture sensors where they represent the root zone
Choose representative management zones, depth bands, and in-row locations before treating a soil-moisture reading as an irrigation decision input.

When feed conversion ratio changes, start with the period
Calculate a comparable period feed conversion ratio, check whether its records support comparison, and investigate what changed without treating one number as a cause.

A Worked Nitrite-Rise Record: What Each Check Rules Out
A worked, hypothetical incident record that uses paired readings and observations to rule out an isolated reading or an ongoing aeration fault, while keeping capacity open.
