> the hardest part was figuring out what, exactly, I had to add to the water to get the plants to flourish.
If you don't want to engineer it from first principles: MasterBlend Tomato[1]. Plants love this shit. I've grown a lot of plants hydroponically using this blend, and also use it to water/feed my soil plants.
> Mix 8 oz. of 4-18-38 in 100 gallons of water along with 5 oz. of Magnesium Sulfate. Completely dissolve. Then add 8 oz. of Calcium Nitrate and completely dissolve.
(At a smaller scale: it's about 12g 4-18-38, 6g Magnesium, and 12g Cal Nitrate per 5 gallon bucket.)
