Canna Boost accelerator with H&g

[GronoBoof]

Im using House and garden aqua flakes and was told by grow shop guys I could get great results adding Canna Boost accelerator, curious if anyone has any feed back on the product?

I am using the canna coco a+b base nutrients with all additives and canna boost accelerator has given me exceptional flower gains but it's very costly.
