CYCO Feeding Schedule: The Platinum Series Grow & Bloom Chart Explained
CYCO is an Australian brand, and its Platinum Series feed chart is published in ml per litre, not ml per gallon like most US-formulated lines. That trips people up before they even get to the actual feeding philosophy, which is its own thing: CYCO's chart runs several products at once from week one, not a simple two-bottle base with occasional boosters. Here's the real chart, in CYCO's own numbers, with the US conversion shown openly rather than silently done for you, plus what actually running the stack costs. We don't upsell.
The 30-Second Answer
- CYCO's numbers are in ml per litre. 1 US gallon is roughly 3.8 litres, so multiply CYCO's per-litre dose by about 3.8 to get ml per gallon.
- The growth phase (weeks 1-6) runs Grow A & B, B1 Boost, and Zyme together from day one, all at 2 ml/litre, not staged in one at a time.
- The bloom phase (weeks 1-8) adds Silica and Uptake immediately, then layers in more boosters from week 5 onward as flowering progresses.
- Dr Repair runs at 1 ml/litre through the entire cycle, start to finish, not just during a specific stage.

The official CYCO Platinum Series feed chart
This is CYCO's own published dosing from their official metric feed chart, in ml per litre of water. We've kept it in CYCO's native units rather than converting it for you, since a silent conversion is exactly the kind of thing that goes wrong; the math to get to gallons is directly below the chart.
The philosophy here is genuinely different from a two-part base like Canna Coco or GH FloraPro. Grow A & B alone isn't really "the" recipe, B1 Boost and Zyme run alongside it from week one at the same 2 ml/litre rate, and Dr Repair runs underneath the entire chart regardless of stage. By the time you're deep into bloom, you're realistically running five or six products in the same reservoir at once. That's not a flaw, it's how this specific line was designed, but it's worth knowing before you buy just the two base bottles and expect the same result the chart shows.
What running the full stack actually costs
Grow A & B and Bloom A & B alone are inexpensive, priced closer to a budget base nutrient than a premium one. B1 Boost and Zyme, the two products CYCO runs alongside the base from day one, cost meaningfully more per bottle than the base itself, in Zyme's case more than 4 times the base price for the same size container. That's the real, honest math of this line: the "core four" (Grow A&B, B1 Boost, Zyme) plus Dr Repair running underneath everything adds up to a genuinely premium total cost, even though the base bottles alone look cheap.
Where CYCO fits if you're used to a simpler system
Growers coming from a two-part base like Canna Coco or GH FloraPro sometimes assume CYCO works the same way with a couple of extra optional add-ons on the side. The chart says otherwise. From week one of both growth and bloom, CYCO's own numbers already have three to four products running in the same reservoir, not staged in gradually as the cycle progresses. That's a genuinely different design philosophy: instead of a lean base you optionally build up, CYCO's Platinum Series is closer to a complete system from the start, where the base nutrient and the core additives were formulated to work as one combined recipe rather than a foundation you customize later.
That's not automatically more complicated to run in practice, once your reservoir is dosed for the week, you're not adjusting daily, but it does mean the real entry cost of "trying CYCO" is higher than just buying Grow A and Grow B and seeing what happens. If you want to test the water first, running the base alone for a cycle will still produce a result and won't hurt anything, it just won't be the specific result CYCO's own chart is built to deliver. For an accurate first impression of this line, budget for at least the base plus B1 Boost and Zyme, not the base in isolation.

What We'd Tell You at the Counter
If you're new to CYCO, the honest starting point isn't just the two base bottles, it's Grow A&B or Bloom A&B plus B1 Boost and Zyme, since that's how CYCO's own chart runs it from week one, not as later add-ons. Test your water first: this chart assumes 0 to 200 ppm starting water, and if yours runs higher, you'll need to pull back your base dose to avoid overshooting your target EC. And do the metric conversion carefully, multiply litres by 3.8 to get to gallons, or just mix in litres if you have a jug that makes that easier, rather than eyeballing a rough gallon eyeball estimate. We sell the core line and are glad to walk through which pieces you actually need for your setup. We don't upsell.
Frequently asked questions
What is the CYCO feeding schedule?
CYCO's Platinum Series runs Grow A & B during a 6-week growth phase alongside B1 Boost and Zyme, all at 2 ml/litre. At the flip, Bloom A & B takes over for 8 weeks alongside Silica, Uptake, and Zyme from week one, with B1 Boost added from week 5 onward. Dr Repair runs at 1 ml/litre through the entire cycle regardless of stage.
How do I convert CYCO's ml per litre dosing to gallons?
Multiply the per-litre dose by approximately 3.8, since 1 US gallon is roughly 3.785 litres. A 2 ml/litre dose works out to about 7.5 ml per gallon. If your measuring equipment is metric, it's often more accurate to just mix in litres directly rather than converting, since rounding during conversion can introduce small errors.
Do I need to run every CYCO product at once?
No, though CYCO's own chart does run several products together from early on, which is different from a typical two-part base system. The base (Grow A&B or Bloom A&B) plus B1 Boost and Zyme is closer to CYCO's actual intended starting point than the base alone. Late-flower boosters like Potash Plus and the specialty additives are more genuinely optional add-ons layered on top.
Why does my water quality matter for CYCO dosing?
CYCO's chart is calibrated for water starting at 0 to 200 ppm. If your tap water tests higher, CYCO's own guidance is to reduce your base nutrient dose (down to 1.5, 1, or 0.5 ml/litre as source water PPM climbs) so your final solution doesn't overshoot the target EC once the base nutrient's own dissolved minerals are added on top of what's already in your water.
What does Dr Repair do in the CYCO line?
Dr Repair runs at a flat 1 ml/litre through the entire cycle, both growth and bloom phases, rather than being tied to a specific stage like most of the other supplements. It's positioned as a continuous-use root and plant health product rather than a stage-specific booster.
Whether you're running just the base or the fuller CYCO stack, the Platinum Series line and the meters to keep your water quality and EC on target live in the Modern Farms catalog. Because, as always, we don't upsell.
