You will need nutrients. I suggest going organic and next run making your own teas and using a cooked soil recipe.
I amend Fox Farms with earth worm castings, perelite, bat guanos, organic fert (tomato tone, Fox Farms all purpose...), powdered rock...

There are a bunch of really smart and friendly people there that have taught me a shit ton about organics.
You should have seen my veggy garden, it went nuts because it got all the left over teas I made for my indoor plants.
Your soil mix should be cooking right now.
If you amend your soil with the super soil recipe, you will not need nutes at all, you can just use tap water.
I switched to organics and it is great. I make my own fertilizers (tea) for much cheaper than the bottled nutes.
It is actually easier than using synthetic nutes and the end product is amazing.
Plus, you get to say things like, "My nugs are organic, brah," and look down your nose at people. It is fun.
