BioBizz All-Mix Feed Chart – Soil Doses per Litre
BioBizz's own published All-Mix schedule for pre-fertilised organic soil. Week by week, in millilitres per one litre of water.
- All dosesper 1 litre
- pH6.2 – 6.5
- Base feedBio-Grow or Fish-Mix at 1ml
Every figure is millilitres per one litre of water, not per ten. Most feed charts are written per 10 litres, so check this one twice. A 10-litre watering can takes ten times what you see here — Bio-Bloom at 2ml per litre is 20ml in a 10-litre can.
Getting it right
- Bio-Grow or Fish-Mix, never both. The two sit on the chart at the same dose because they are alternatives, not a pair. BioBizz say to replace Bio-Grow with Fish-Mix through the vegetative weeks, then switch to Bio-Grow when you want to trigger flowering. Run them together and you double the nitrogen.
- Root-Juice is Grow 1 only. 4ml per litre in the first week, and it does not appear again anywhere on the chart.
- All-Mix is already fertilised. The soil carries its own food for the first few weeks, which is why the base feed does not start until Grow 2 and stays at 1ml per litre the whole way through.
- Bio-Bloom starts at the flip. 1ml at Flower 1, then 2ml, 2ml, 3ml, 3ml, and 4ml for Flower 6, 7 and 8.
- Top-Max steps up late. It runs at 1ml per litre from Flower 1 to Flower 5, then jumps to 4ml for the last three weeks.
- Bio-Heaven and Acti-Vera run all the way. Both start at 2ml per litre in Grow 1 and climb to 5ml by Flower 6. They are tonics, not a feed, so they sit alongside whatever base you are running.
- Keep pH between 6.2 and 6.5. If your system controls pH for you, hold it at 6.2 to 6.3. Soil buffers a little, but feed still locks out at the wrong number.
- Soft water needs CalMag. On reverse osmosis or very soft tap water, BioBizz recommend CalMag at every watering. It is on a separate table on their sheet rather than this chart, so follow the dose on the bottle you own.
- The flush week is plain water. Every row on the chart stops.
- Under-feed rather than over-feed. BioBizz's own advice is that a plant recovers from too little, but rarely from an overdose.

Common questions
Is this per litre or per 10 litres?
Per one litre. Root-Juice at 4ml means 4ml in a 1-litre jug, or 40ml in a 10-litre watering can.
Do I run Bio-Grow and Fish-Mix together?
No. Pick one. BioBizz suggest using Fish-Mix through the vegetative weeks and moving to Bio-Grow when you want to trigger flowering. Both rows show the same dose because they are two ways of doing the same job.
Growing in Light-Mix or coco instead?
Different chart, higher doses. See the BioBizz Light-Mix and Coco-Mix feed chart.
Why does the chart restart at 1 when flowering starts?
BioBizz number their own sheet WK1 to WK12 straight through. Growers count flowering from the flip, so ours restarts there. Their WK1–2 is our Grow 1–2, their WK3–10 is our Flower 1–8, their WK11 is the flush and WK12 is harvest.
Do I need CalMag?
On reverse osmosis or very soft tap water, yes — BioBizz recommend it at every watering. It sits on a separate table on their sheet, not on this chart, so use the dose printed on the bottle.
What goes in during the flush week?
Plain water. Every product on the chart stops.
