i don't think nutes make a huge difference. maybe start with general hydro, and if you aren't impressed, go with something fancier. ultimately, you are delivering the exact same macro (N, P, K) and micro nutrients, regardless of how pretty the picture on the bottle is.
it does get a little more complicated than that. there are plenty of other additives you'll need: beneficials, H2O2, enzymes, etc. so save your money when it comes to nutes so you can spend on all that other stuff when the time comes, which will be real soon.
