Anyone have a recommendation for a fertilizer to try? I have home depot and lowes nearby but have yet to find a good hydroponic store that will carry the designer products (ie: foxfarm line)

This is my first grow so I was trying to go without nutes as much as possible to get a base knowledge then the next crop (just started on Friday) I was going to start with something of a fertalizer set anyways, so I just need to know what to get.

Thanks for all the advise.
