Canna FAQ's
It depends entirely on your substrate. Coco A&B for coco coir, Terra Vega and Flores for potting mixes and soil, Aqua Vega and Flores for recirculating hydroponic systems, and Classic for run-to-waste setups on inert media. CANNA formulates each line for how that medium behaves, so the names are effectively the instructions — this is not a case where one bottle covers everything.
Both are hydroponic nutrients, but Aqua is built for recirculating systems where the same solution returns to the tank and is reused, while Classic is for run-to-waste setups where fresh solution is fed and drained away. A recirculating solution changes composition as plants feed from it, and Aqua's formulation accounts for that. Using Classic in a recirculating tank tends to cause drift.
Usually not. Unlike most coco nutrients, CANNA Coco A&B is formulated with coco's calcium and magnesium binding already accounted for, so a separate cal-mag is often unnecessary. The exception is very soft or filtered water, which starts with almost no calcium — that is what CalMag Agent is stocked for. Check your water before adding it by habit.
It is an enzyme product that breaks down dead root material into sugars the plant and its beneficial microbes can use. That matters most in media you intend to reuse and in recirculating systems, where decaying roots otherwise foul the solution. It is not a feed and will not fix a nutrient problem — think of it as maintenance for the root zone.
In the flowering window, and briefly. PK 13/14 is a concentrated phosphorus and potassium supplement designed to be run for a short period rather than continuously, and it overlaps with Boost Accelerator in timing. Running both at full dose, for weeks, is the classic way to lock out other elements. Follow CANNA's chart and change one thing at a time.
