Solution:

• Check spelling of reagent name
• Add necessary reagent manually via the "Don't have the reagent you need?" link

Incorrect reagent mass calculation

Problem: System shows incorrect quantity for preparation

Solution:

• Ensure the volume of finished fertilizer is specified correctly
• Check target element concentrations

Recipe doesn't save

Possible reasons:

• Required "Recipe name" field not filled
• No reagent selected
• Concentrations not specified
• Component solubility limits exceeded

Element conflict in composition

Reason: Mutually exclusive element forms selected (e.g., Fe²⁺ and Fe³⁺ simultaneously)
