Canna Nutrients, which type?

I've been looking through what nutrients I should buy and I decided Canna nutrients look good for me.

So here is my question, I use hempy buckets for growing - should I use Canna Aqua or Canna Substra? Aqua is the normal hydroponic solution, Substra is for for run-to-waste systems for inert substrate.

I appreciate any help.

I could still use some help if anyone knows

Just use the aqua.
