SECRET Fertilizer :) My 'fertilizing cocktail' consists of mixing 1/2 bottle of cheap beer, 1 tablespoon of Epson salts, and 2 tablespoons of fish emulsion in a watering can (1-2 gallons). I do this to ALL my vegetable, flowers, and indoor plants. You will definitely notice the difference in a few weeks! Don't waste too much money on the beer. Cheapest still works great -- plants aren't picky!
Basically, a good rule to remember is that if you grow a plant for the fruit or the root, it needs full sun. If you grow it for the leaves, stems, or buds, a little shade will be just fine.
Maybe someday when we have a lot of land!
