Is This a Good Soil to Use?

Hello, I'm about to buy this soil from canadian tire called " Premier Pro mix "

Heres a pic- http://www.canadiantire.ca/AST/browse/2/OutdoorLiving/FertilizersGrassSeed/SoilsMixes/PRDOVR~0594888P/Premier%2BPro-Mix%252C%2BPotting%2Band%2BSeeding%2BMix.jsp?locale=en

& Some info on it:
High quality, lightweight components give it good water retention and excellent drainage
Multi-purpose growing mix for seed starting, planting and transplanting into indoor and outdoor containers
Contains Canadian sphagnum peat moss, coarse perlite, vermiculite, macro and micronutrients, limestone (for PH adjustment) and wetting agent
Keep Pro-mix moist for first several weeks after transplanting
During growth, plants will need nutrients in the form of fertilizer (2-3 weeks after transplanting)
85 L bag

Is this soil good to use by itself, or should I mix anything in like perlite etc.

Half bail Pro mix
1 bag of fox farm ocean forest
1 cup blood meal
1 cup bone meal
1/2 cup kelp meal
1 cup dolimite lime

If you can toss in worm castings too if ya can get them,can't go wrong with adding them.In above mix toss in about a gallons worth or so,it dosen't have to be perfect on the amount.

Do you have the pro mix bx or the hp?The hp has more perlite than the bx.If you use the bx version add a bit more perlite to the mix,about 2-3 gallons worth.

This is a water only mix......yes water only is all you need.

Or you can not add shit and work wit bottled nutes.

I live in canada and we do not have foxfarms products around here, I also plan on just using bottled nutes. Do you think I would be fine just mixing promix with perlite and wormcastings? If so howmuch percentage wise.

Yes you'll be fine with that.

BX or the HP on the pro mix?If it's HP you don't need the perlite.If BX i would go with a 15%.The worm castings.......half gal.....1 gal.....1 1/2 gal.Ain't gotta be too picky on the castings.
