I would start off and just get the Canna A&B and the Rhizotonic. Why? Because you're too novice to go spending money on nutrients that you probably wont use properly, that will at best be a waste of money, and worst will damage your plants because of over feeding etc.
In the beginning I'd highly recommend using just the basic base feed nutrients. You can easily grow a plant that has decent size crystally buds all over it with just the A&B. Once you've done a grow with just A&B and it goes well and you recorded what you did, you can replicate this and look at add/change one thing on the next grow.
I'd start off lightly feeding them A&B and give them lots of Rhizotonic for the first 3 weeks. Whatever it says on the Rhizotonic bottle 4ml per litre? Something like that.. then give them 2ml per litre for week 4 and 5, then 1ml per litre weeks 6, 7 and then stop feeding them Rhizotonic. Why? Because root stimulants always work best when there's less nutrient in the soil and as time goes on you don't want to be wasting your Rhizotonic. In the last few weeks the roots stop growing and basically the plant starts to prepare to die.
Cannazyme while okay is not neccessary. In my opinion when you first start growing a new way, you don't want to go spending lots of money on things that aren't absolutely neccessary. You are better to make it as simple as possibly, get a grasp of the fundamentals and work up slowly from there.
If you see any deficiencies from say day 7 - 21 it's probably cal/mag related so give them a dose of cal/mag as soon as you see any yellowing of the lower leaves or brown spotting of the upper leaves.
On your second grow, if the first goes well, I would upgrade to adding PK 13/14. If that second grow goes really well, then I'd upgrade to adding Boost. But really you don't need it. I got very nice buds using just A&B on my first grow with Canna and it was easy and problem free. I think over complicating things when you really dunno what you're doing is worse than it is good.
