AN, GH, Canna, Atami, Dutch pro, whatever!
Nutrients are a small part of growing.
Available CO2, temps, humidity, genetics, ph, grower skill, available useable light. Get any of these wrong and the best gold plated nutrients in the world wont make up for it.
Concentrate on the basics and the nute brand wont matter. After all, plants cant read whats on a label. Just make sure its formulated for weed. You need one formulae for veg, a different formulae for flowering and some kind of boosters towards the end of flower, pk13/14 and some kind of carb load such as molasses but formulated for hydro.
All can be bought on ebay for around £40 ($60) but will last for much more than one grow.
