Is Canna Trace Mix a complete fertilizer?

No. It supplies only trace elements: iron, manganese, boron, zinc, copper and molybdenum. You still need a base nutrient for nitrogen, phosphorus, potassium, calcium and magnesium.

When should I use it?

Canna lists it for blooming. Many growers add it through flower development, when trace-element demand rises, rather than as an all-round feed.

The label gives 10 to 20 ml of concentrate per 10 litres of water, a dilution of about 1:1000 to 1:500. Start at the lower rate and watch the plants.

Can I use it with other Canna products?

Yes. It is designed to sit alongside a base nutrient line. Add it to the reservoir after the base nutrients are mixed and pH is adjusted.

What happens if I overdose it?

Trace elements are toxic in excess. Too much can burn tips and lock out other nutrients, so measure carefully and do not stack it with other micronutrient products.

Does it fix yellow leaves?

Only if the yellowing comes from a trace-element shortage such as iron or zinc. Yellowing from nitrogen, magnesium or pH problems needs a different fix.
