Nutrient Uptake

Nutrient uptake depends on root health, available ions, pH, EC, water movement, oxygen, temperature, and media behavior. A plant can show nutrient-like symptoms even when nutrients are present.

Leaf Nutrient Symptoms pH & EC Card

What to learn

Roots absorb nutrients from the solution around them.
pH influences which nutrients remain available.
High EC can increase osmotic stress and reduce water uptake.
Low oxygen, saturation, damage, or cold roots can reduce uptake.
Deficiency, lockout, and root stress can look similar above ground.

Rule: Do not correct nutrient symptoms without checking root-zone context.

Measurements to pair

Feed pH, runoff/slurry pH, feed EC, runoff EC, substrate moisture, irrigation timing, media type, root-zone temperature, and recent feed changes.

Grow Doc prompt

I am evaluating nutrient uptake. The symptom looks like [chlorosis/necrosis/curl/slow growth], feed pH is [x], EC is [x], runoff/slurry is [x], media moisture is [x], and root-zone context is [x]. Help separate deficiency from lockout or root stress.
