Biobizz Feed Chart 2026: All·Mix and Light·Mix Schedules
Greens Horticulture ·
The Biobizz feed chart week by week, from Biobizz's 2026 UK nutrient schedule. There are two versions: one for Light·Mix or Coco·Mix, which carry little food of their own, and a lighter one for All·Mix, which is pre-fertilised.
All doses are ml per litre of water, apart from Microbes, which is grams per litre.

Notes from Biobizz
- * The veg stage can last as long as you need it to: repeat the veg doses.
- Bio·Grow and Fish·Mix do the same job, so use one or the other, not both. You can use Fish·Mix during growth, but switch to Bio·Grow for flowering: it carries food for the beneficial microbes and is meant to run through veg and flowering.
- Microbes go in once a week, or twice a week when the plants are feeding hardest in veg and flowering.
- Week 9 is plain water only; week 10 is harvest.
- Alg·A·Mic, Acti·Vera and Fish·Mix can also be sprayed on the leaves 1-3 times a week until the second week of flowering: 1-2 ml per litre of each if you use one or two of them, no more than 1 ml per litre of each if you use all three.
- Hard water: Biobizz suggest their Bio·Down to lower the pH. To raise it, Bio·Up. Soft or RO water: Biobizz CalMag. Pest problems: Leaf·Coat.
Getting started with Biobizz
- Pick your soil first: All·Mix feeds the plant for the first few weeks, Light·Mix leaves the feeding to you and suits seedlings and cuttings.
- Pre·Mix and Worm·Humus are Biobizz's own ways to enrich a soil before you plant.
- Organic feeds work with the life in the soil, so give them time: go by the chart rather than chasing a number on an EC meter.
- Browse the whole Biobizz range or our premium soils.
