In hydroponics the plant feeds entirely from the water, so when something goes wrong, the cause is almost always in the numbers.
I wrote this to take you from the symptom you can see to the cause and the fix, instead of guessing and piling on more nutrients.
Inside you’ll find a diagnosis table (symptom to cause to fix), the pH and EC/PPM target chart by crop, a “read the leaves” deficiency guide that tells you which nutrient, and, more often than not, that pH is the real problem, the right way to mix and adjust a reservoir, and the hidden causes most guides skip: water quality and root-zone temperature.
The message throughout is simple: check pH and oxygen before you add anything.
