You want simple?
Rapid Start and FloraNova Grow for veg and FloraNova Bloom for flower.
buy some General Hydro Ph Up and Ph Down, a Ph/ppm/ec meter and your good to go.
FloraNova get's hated on but it's a great product. People find a lot of excuses to diss on it but do some reseach. FloraNova always gives me happy and healthy plants. Forums are filled with people who never used anything but Canna or House and Garden, or Advanced so they swear by them and because they pay way more then everybody else and they have a couple harvest under their belt, they think every drop of snake oil they bought is the reason for their success.
Or they spend so much money on this or that it has a placebo effect-it MUST of done something, "If my buds look like this and I spent $$$ then they wouldn't of looked that way if I didn't"
I use a lot more stuff then I mentioned, but it's more because I enjoy the hobby. Additives only work when you know how to use them. Additives have injured many a newb and hobbist's plants.
Keep it simple. Root stim and base nutrients. You don't need anything else for your first run-anyone who tells you other wise, or trys to say you need more just doesn't understand how plants work.
Here's proof. Go look at a body building magazine, you'll probably get a good laugh at how 90% of the magazine is advertisement for supplements(and how similar it is to the hydro mags they give you everytime you leave the hydro store), a lot of them even have graphs and site scientific studies to back their claims. They also have guys on steriods claiming certain supplements are their sercret, just like the fertilizer industry. NONE of those supplements work, and the few that have any effect at all are minimal-the only way to build muscel is to work out and eat calories, yet the supplement industry is massive and the people who use all these supplements and go to the gym everyday swear by them. "Hey, just look in the mirror pal, you think i'd have these 24" pythons if wasn't taking my $500.00 P90x Extreme Horny Goat Muscle Tonic?"
