Canna PK13/14

[QBCrocket]

Hi Guys
what is the reason for the warning 1 week only on the Canna PK13/14 , what will happen if I go over the week will my buds get to big and to tasty?

Cant answer the original question but can add to it a bit. Fish bone meal 16, coconut water 20 and their both organic and work together well in a tea.

I got a bunch of canna / bio-canna left overs I intend to dump on the compost pile this spring.
