Canna Users / Advice

I read a post from Stinky where she mentioned the Canna Line giving it good reviews. On that, I purchased the Canna Terra vega and Flores. This is going to be my first time to grow with soil. My medium is Promix BX. I am going to stagger the potting stages to keep the Ph in check. She mentioned that new growers should probably stay away from additives until more experienced. However, I have a couple hydro grows under me that went very well. Having said that I still think that what I purchased would take me to the harvest with great results. I still might purchase the PK 13/14 when flowering. My question is that the N levels in the vega dont seem as high IMO but then again what do I know but I have a bag of dried blood meal 15-0-0 and was wondering if I could use this in conjunction with the Canna product without adverse effects. Just to kick up the N levels a bit. Any comments or suggestions or additional info regarding the Canna line would be appreciated!
