Canna A+ B

[rsrick]

Hi there first time growing in coco. Using a+ b and some cal mag. Just wondering do I have to change the nutrient rario when my autos go into flower. It's says on the bottles not to but just wanted to put it out there cos it seems strange to me . Thanks in advance

I have flora duo a & b and it definitely has a different ratio for both semesters.
