Getting your nutrient dosing right is one of the most important factors for a healthy, high-yielding grow. Too little and your plants underperform; too much and you risk nutrient burn, lockout, or root damage. Our Zamnesia fertilizer range takes the guesswork out of feeding by offering carefully balanced nutrient programs for every type of grower. Use the calculator below to instantly generate a personalised, week-by-week schedule tailored to your batch size.
Choose the right program for your grow
Before you start, it helps to know which fertilizer fits your setup best:
All-in-One Liquid: A complete, single-bottle nutrient for photoperiod plants grown in soil or coco. Simple, fast, and reliable.
All-in-One Autoflower: The same convenience as our All-in-One Liquid, but with adjusted EC targets optimised for the shorter life cycle of autoflowering strains.
Vegan Grow & Bloom: A two-part organic formula for growers who prefer a fully plant-based approach. Delivers rich flavour and clean smoke.
Monster Bud Mix: A granular all-in-one fertilizer mixed directly into your soil before planting. Ideal for low-maintenance grows in regular potting soil.
Monster Bud Mix – Living Soil: A stronger granular blend formulated for Living Soil setups, where beneficial microbes do much of the feeding work for you.
Each program works best when paired with our PK 13-14, Max Flavour, and Max Yield boosters during flowering. The vegan range uses our Vegan PK booster instead of PK 13-14.

Tips for best results
Always measure your EC. An EC meter is your best friend. After mixing your nutrients, check that the EC matches the target value in the schedule. If it's too high, dilute with more water. If it's too low, add a little more base nutrient.
Check your pH. Cannabis absorbs nutrients best when the pH of your feeding solution sits between 5.8 and 6.5 (soil) or 5.5 and 6.2 (coco/hydro). Use our pH- to lower pH or our pH+ to raise it.
Start low, build up. If you're new to a program or unsure how your plants will react, start with a slightly lower dose and increase gradually over a few feedings.
Mix in the correct order. Always add your base nutrients to the water first, mix thoroughly, then add any boosters one at a time.
Flush before harvest. A proper flush in the final week removes excess salts and improves the taste and smoothness of your final product.
Observe your plants. Schedules are a starting point, not an absolute rule. Yellowing, browning tips, or slow growth can all indicate that a small adjustment is needed.
