Well, I only have experience with the General Hydroponics Flora Series but find them to be quite good. They are a 3 part liquid that you need all 3 parts to make work. Just not the cheapest on the market.

You will want to make sure that you get a pH testing kit, some pH up and pH down. Test the pH of your nutrient solution daily and adjust if needed. If the pH level is to high or low for the plants you are growing, your plants can starve even with the best nutrients. Fortunately you can get a pH testing kit for about $8 and the "pH up" and "pH down" is not expensive either, but it's important to check it daily.

Salts (chemistry) should not be confused with salt as in table salt, sodium chloride (NaCl).

Fortunately Epson salt, also known as Magnesium Sulfate (MgSO4·7H2O) is not toxic at all as it is a compound that is contained (in large quantities) in literary every nutrient solution, except some "bio", where Mg is provided through Magnesium Carbonate extracts. Many other compounds of a nutrient solution are actual salts.

If the Mg content and the Sulfur content (epsom salts contains much Sulfur) of a nutrient solution is sufficient, there is no need to add any epson salt.

I am calculating, and mixing my own nutrient recipes from scratch using basic raw materials and compounds. I am also doing 'independent' research on formulas for specific plants, mainly capsicum varieties, amaranths and other tropical edible plants and bushes.
