ahhhhh now we have something :D help me help you brother...
when i used to run canna back in the day, i pretty much followed the chart to the t, on normal feeding...and then i would cut back from there *if need be*
you may need some cal/mag fasho...5ml/gallon is a good starting ratio and work ya way up if they are asking for it.
far as the regen a root, headmasta, and alg-a-mic... never really played with those, im guessing they are rooting supplements and something with algae extracts in, right? you can follow the bottle or cut in half
i had pulled out my logs from back in the day when using canna, but when i just looked at the chart again, they were pretty much spot on.
