Seedling EC Target Lookup

Audit actual final nutrient-solution EC against caller seedling-stage band; distinct from source-water ceiling and temperature compensation, no nutrient-ion sufficiency or universal dosing target.

Description

Final nutrient-solution EC differs from source-water EC.

Final nutrient-solution EC differs from source-water EC. A verified seedling-stage band defines this local check.^[1]

Enter aligned nonempty unique stage IDs/nonnegative minima/maxima, exact query and nonnegative observation list. Validate selected ordered band; return limits and outside indices.

When to use Seedling EC Target Lookup

Use Seedling EC Target Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. Empty observations are allowed. No nutrient sufficiency, universal dosing target or temperature correction is supplied.

Prepare measured container, labor, environmental or inventory records and independently verified stage limits requested. Keep units, temperature conditions and dates consistent.

How to use Seedling EC Target Lookup and understand its results

Prepare measured container, labor, environmental or inventory records and independently verified stage limits requested. Keep units, temperature conditions and dates consistent.
Enter callerSeedlingStageIds, callerFinalSolutionEcMinimum, callerFinalSolutionEcMaximum, querySeedlingStageId, observedFinalSolutionEc using the field table and calculation rules, then run the tool.
Read callerFinalSolutionEcRange, solutionSamplesOutsideCallerEcIndices. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
callerSeedlingStageIds	Caller seedling stage ids	list of string	Required
callerFinalSolutionEcMinimum	Caller final solution ec minimum	list of number	Required
callerFinalSolutionEcMaximum	Caller final solution ec maximum	list of number	Required
querySeedlingStageId	Query seedling stage id	string	Required
observedFinalSolutionEc	Observed final solution ec	list of number	Required

Enter aligned nonempty unique stage IDs/nonnegative minima/maxima, exact query and nonnegative observation list. Validate selected ordered band; return limits and outside indices.

outside=observedEC<selectedMin OR observedEC>selectedMax

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
callerFinalSolutionEcRange	Caller final solution ec range	list of number
solutionSamplesOutsideCallerEcIndices	Solution samples outside caller ec indices	list of number

Limitations and assumptions

Empty observations are allowed. No nutrient sufficiency, universal dosing target or temperature correction is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Source Water EC Threshold Lookup: Source-water EC screening needs a verified crop-stage ceiling and known measurements. Missing EC observations are not passing values. For a complementary task, use Slow Release Months Rating Lookup: Release-duration records are tied to measurement temperature. Elapsed time can exceed the rated period and produce a signed deficit.
