Dude fuck the noise. Get yourself some Advanced Nutrients and call it a day.
Expensive? Yes, but very easy to use and gives you top shelf buds and killer yields. Just get your base nutes (3-part, 2-part...whatever) for the medium you're growing in (soil/soil-less/coco/rockwool etc) and get a few additives like a good root innoculant/beneficial bacteria (Voodoo Juice, Great White, Roots Excellurator by House and Garden), a Silica boost to help the plant grow stronger and fight heat, mold/fungus, and pests. B-52 (b vitamin suppliment) for transplanting, clones and helping the plant efficiently make and use carbohydrates. It also has humic and fulvic acid which plants love. And a bloom booster like Overdrive or Big Bud.
And if you have the cash, maybe a carb boost/flavor enhancer like Bud Candy or Kushie Kush. A lot of people like to use a flushing solution the last week or few days too to wash out some of the salt thats accumulated over time. So if you want to do that then get some Final Phase also.

Expensive right? That's the biggest complaint with AN. That it's not worth the price. I think it is, but that's me.
