Atami B’cuzz feeding schedule: choosing, dosing and mixing

Start with the medium and nutrient range

Write down the names on your bottles before choosing a schedule. B’cuzz Soil A&B is for soil and potting compost, Coco A&B for coco coir and Hydro A&B for hydroponics. Copying a coco schedule into a soil setup is not a useful shortcut: the medium helps determine how you prepare the feed.

Check whether you use B’cuzz A&B, 1 Compo or ATA Terra. 1 Compo is a base feed for growth and flowering in calcium-rich soil. With ATA Terra, Leaves is for vegetative growth and Max for flowering. Switching stages in ATA Terra therefore means something different from adjusting an A&B dose.

Match the schedule to your additives

List the additives you actually need alongside the base feed. Root Stimulator and Rootbastic target the start and root development, but have different doses and application periods. Bloom Stimulator is used from flower formation; Coco Bloom Stimulator is the coco version. Do not put every bottle into every week.

Bloombastic is intended for the final four to six weeks of flowering and ripening alongside base nutrients. Avoid combining it with another PK feed such as PK 13/14. Stacking phosphorus- and potassium-rich products can make the solution too concentrated. Choose one suitable programme and account for the EC of the complete mix.

Calculate A and B separately

Use the water volume you actually prepare, rather than the tank’s maximum capacity. For each component, multiply the dose in ml per litre by the number of litres of water. Keep A and B on separate lines.

A calculation example, not a recommended dose: if your appropriate schedule calls for 2 ml A and 2 ml B per litre and you prepare 10 litres, measure 20 ml A and 20 ml B. Do not split 20 ml between the bottles. Select the actual dose for your schedule, stage, water and medium. With Soil, the nutrients already in your potting compost also matter.

Add concentrates separately to water

Measure the water into a clean tank. Add one component, mix thoroughly, then add the other separately and mix again. Never pour undiluted A and B together into a measuring cup. Separate bottles prevent nutrients from reacting while highly concentrated.

Using silicon, CalMag or other supplements as well? Check the complete mixing sequence for the exact products. An instruction for the A&B pair is not a universal sequence for every bottle. Use clean measuring equipment and keep one concentrate out of the other’s storage bottle.

Measure the finished solution

Check EC and pH after thoroughly mixing the products you selected. Compare the readings with the schedule for your medium and growth stage. A single fixed EC or pH target will not suit every plant and system. Adding feed to heavily fertilised compost is also a different decision from feeding a medium with very few nutrients.

Record the date, water volume, products, doses and final readings. If plants react unexpectedly, check preparation, watering and the system first. Change one purposeful step so you can understand its effect. Our pH and EC guide explains the role of both readings.

Buy the amount you will use

Choose bottle size from the number of mixes and dose. A larger bottle does not change the concentrate needed per litre of water. Consider the application period and storage instructions on your packaging as well. Browse all Atami and B’cuzz nutrients to choose your base feed and any additions.
