your first grow i would go with
general Hydroponics Flora series, the Flora Nova is great it's what I use
you can buy on e-bay flora grow, flora micro, flora bloom like a 8oz kits all 3
really cheap. that will give you time to see whats up with the other nutrients
like fox farm, dutch masters, advanced nutrients.
You don't want to spend 300 - 400 on some nutrients, and find out you really
don't like them. I'd start off simple and add to it, buy a small amount and try it. If you like it, buy a larger amount.
I recomend Advanced Nutrients Dr Hornby Big Bud (you can find 25gram packets on e-bay for like 8 bucks)
the first 4 weeks of flower and General Hydroponics Kool-Bloom the last 3-4 weeks.
