Hey Growmie,
Being prepared is a key component to a successful grow. Before I even put anything in the soil I know everything that I'll be using and make sure it's on hand. As far as suggestions nutrients I would go with General Hydroponics Flora Grow, Bloom, Micro Combo Fertilizer set, easy to get, and very easy to use.
Hopefully, this was helpful and remember ..."Happy Growing" and "Free your mind one puff at a time.
