Every figure is millilitres per one litre of water. A 10-litre can takes ten times these numbers, so 1.5ml here is 15ml in a 10-litre can.
Getting it right
- Gold Label publish a start, change and stop schedule. Their own page gives you a dose on the week it begins, then only tells you when it changes or when it stops. A dose runs on unchanged in between. The grid above shows it week by week, so you can read one line and go.
- Flowering begins at Flower 1, the fourth week of Gold Label's schedule. That is where their schedule drops from eighteen hours of light to twelve, so the three weeks before it are Grow 1 to Grow 3 and everything after is Flower.
- A and B is one dose, twice. At 1.5ml that is 1.5ml of Coco A and 1.5ml of Coco B into the same litre — not 1.5ml shared between them. Add A, stir it in, then add B.
- Coco holds no feed of its own. That is why the base starts at Grow 1 on this chart rather than later, and why the dose is repeated at every feed rather than once a week.
- Ultra Enzyme runs every other week. Grow 2, then Flower 1, Flower 3, Flower 5 and Flower 7. The gaps are deliberate — it is a root-zone cleaner rather than a feed, and Gold Label alternate it on and off.
- Ultra PK opens at a quarter of a millilitre. 0.25ml at Flower 1 and Flower 2, then 0.5ml from Flower 3 until the base tapers off. It is easy to over-pour at that rate, so measure it rather than counting drops.
- The feed comes down before it stops. 1.5ml is the ceiling at Flower 4 to Flower 6, then 1.0ml at Flower 7 and 0.5ml at Flower 8. Ultra MG stops after Flower 6 and Ultra Roots after Flower 1.
- The last column is plain water. Nothing from the chart goes in the tank that week.

Common questions
Does this chart cover coco/perlite 70/30 as well as straight coco?
Yes. Gold Label publish one schedule for both. If you are on their HydroCoco 60/40 or 80/20 mix, that is a different blend with its own chart and different doses.
Where does flowering start on this chart?
At Flower 1, which is the fourth week of Gold Label's own schedule. That is the point where they switch from eighteen hours of light to twelve, so the three weeks before it are shown as Grow and everything after as Flower.
Is Ultra Roots the same bottle as Gold Label Roots?
Yes. Gold Label's schedule uses the Ultra range names while the bottle on the shelf is labelled Gold Label Roots. The same applies to Ultra Enzyme and Gold Label Enzyme.
Do I feed this once a week or at every watering?
At every feed. The figures are a mix strength, not a weekly total, so a Flower 4 tank is mixed at 1.5ml per litre every time you make it up.
Why is Ultra Enzyme blank in some weeks?
Because Gold Label alternate it. On this chart it runs at Grow 2, then Flower 1, Flower 3, Flower 5 and Flower 7, and is left out in between.
