canna lineup from seed start , when and how much should i feed

hi im starting a grow with canna lineup , i would like to know which and how much i should use for a Liter water ( i have RO water )
i grow in rockwool and im asking how much i should for sprouting that means from seed start
On their site it says 3.4 ml from terra vega , it doesnt say if A+B in total is 3.4 ml or just 1 bottle is 3.4 ml
Aqua vega 3.4 ml , 4ml rhizotonic for 1 Liter water and no canna zym i guess until later?
