Cyco Platinum Series Feeding Schedule

About Cyco Platinum Series

Cyco is an Australian line and the Platinum Series is its pharmaceutical-grade programme — the pitch is purity, with mineral inputs refined well beyond the usual horticultural standard. In practice that means very clean solutions and very predictable EC, which is why it appeals to growers running tight recirculating systems.

The programme is longer than most: Grow A and B, Bloom A and B, Swell, Potash Plus, Silica, Zyme, Uptake, Kleanse and XL. It is not the cheapest way to feed a plant, and it is not meant to be.

Cyco's own chart marks a “Flush with Kleanse” reminder across Growth weeks 2–6 and Bloom weeks 1–8 (shown here as a note rather than a data row, since it is an instructional band rather than a per-week dose).

Cyco's chart also prints a base-nutrient reduction guide for poor-quality source water: reduce Grow/Bloom A&B by about 1.5ml if your water tests near 800ppm, 1ml near 600ppm, 0.5ml near 400ppm, or use the standard rate under 200ppm.

Dr Repair (Advanced programme): Cyco's chart gives this as a flat rate used through the whole cycle — 1ml per litre — rather than a week-by-week amount, so it is not in the grids above.

Grow XL (optional): Cyco's own chart warns this “will significantly increase PPM and lower pH (please monitor your pH)” and doses it by a water-quality reduction guide rather than by week — roughly 1.5ml less base nutrient near 800ppm source water, 1ml less near 600ppm, 0.5ml less near 400ppm, standard rate under 200ppm.

Cyco's own chart also marks a “Flush with Kleanse” reminder across Growth weeks 2–6 and all of Bloom, plus a final full flush with Kleanse before harvest.

DWC — deep water culture

DWC runs a slightly lower pH range (5.5–5.8) than Cyco's Basic/Advanced media charts (5.5–6.2) — taken directly from this chart, not carried over from the other charts.

Cyco's own chart marks a “Flush with Kleanse” reminder across Growth weeks 2–6 and Bloom weeks 2–8, plus a final full flush with Kleanse before harvest.

Supa Stiky, Suga Rush and Swell are listed on Cyco's own chart under an “Optional” heading for increased flowering, on top of the standalone Single Bloom powder.

Cyco's own chart marks a “Flush with Kleanse” reminder across Growth weeks 2–6 and Bloom weeks 2–8, plus a final full flush with Kleanse before harvest.

The source PDF also lists a cost-per-gallon table by container size (5kg / 20kg), but that section's text is interleaved with a rotated sidebar graphic and could not be read with full confidence, so it has been left out rather than guessed at.

A dash means Cyco’s own chart lists nothing for that product at that week. Figures come straight from the text layer of Cyco’s own PDFs (the same four files linked on this page) — none were image-only, so nothing here was transcribed by eye. Feeding charts are recommendations only; adjust for your own water, medium and environment.
