A practical buying and usage guide for the active CATALYX range, organised by stage, function, watch signs, and product role.
Base nutrient A
Use as the paired Part A base during vegetative growth and base-feed periods.
Strong green growth / Stable EC response / Leaf tip burn after aggressive increases
Base nutrient B
Use with A-X PRO as the paired base nutrient system.
Even canopy color / Stable pH after mixing / Salt buildup in dryback-heavy media
Trace + micros
Use when vegetative growth needs trace and micronutrient balance.
Interveinal color / New growth tone / pH drift after additions
Root stimulator
Use at seedling, transplant, and early vegetative establishment.
Root-zone moisture / Transplant response / New shoot vigor
Bloom booster
Introduce gradually in early flower and maintain through mid flower as appropriate.
Leaf tip response / Flower set / Runoff EC trend
Trace mineral support
Use during early flower transition and late flower trace support windows.
New growth tone / Flower development / Stacking with other micros
