Canna Coco A+B and Promix HP

First time grower. Starting a tent, plan on growing 4 plants and already bought a bunch of stuff including promix HP, Canna Coco A and B, canna rhizotonic, and Canna Boost. Having trouble understanding the feeding schedule, not sure how often to feed... daily, weekly, idk. Thanks for any advice.

*Not opposed to switching mediums either, whether it be coco and perlite, soil etc

I use Promix HP and feed every watering as plants need water

Find a feed schedule online for soil, use that

Canna has a feeding calculator on their website:

It gives you specific instructions almost to the week for how much to use of each of their products.
