Mills Nutrients Feeding Schedule
About Mills Nutrients
Mills is a Dutch-designed line that leans heavily on organic chelation — the nutrients are carried in a form the plant can take up without the medium needing to be perfectly dialled first. In practice that means it is unusually tolerant of a pH that drifts, which is why it has a following among coco growers.
The programme is short: Basis A and B as the base, then Start-R, Vitalize, C4 and Ultimate PK as the cycle progresses. Nothing in it needs to be run at the same time as everything else, and the bottles are concentrated enough that a small kit goes a long way.

A dash means Mills’ own chart lists nothing for that product in that week.
The Target EC row is not a product dose — it is the electrical-conductivity range Mills prints for that week as a mixing check, identical across the tap and osmosis versions of each line.
Figures as published by Mills Nutrients (Regular-MILLS_A5-SCHEMA-FLYER_EN-2.pdf and MILLS_HC_A5-SCHEMA-FLYER_EN-182.pdf), values per 1 liter of water as printed (comma decimal separators kept as Mills prints them, e.g. “2,5ml” = 2.5 mL). Feeding charts are recommendations only. Adjustments may be needed based on environmental conditions, your grow structure, and any additional products you run. Actual results vary.
