This is a difficult question to answer, since everyone's grow is going to have variables that influence the ppm their plants need. Different strains are hungrier than others. What burns one strain might starve another. The more light you provide generally the more a given plant will be able to metabolize, thus two plants that are clones could need completely different ppms if they're in different light outputs.
Here's how each grower finds out for themselves what their plants need. You start by looking at the manufacturer's recommended feeding schedule. Then, since they're almost always stronger than your plants will like, cut that number in half. Try that feeding rate and see how your plants respond. Naturally, for younger, smaller plants you'll feed even lighter so if your nutrient label doesn't have a "seedling" or "small plant" feeding rate, cut it by half again (one quarter strength) until your plants are more mature.
Provided your plants seem happy and healthy, you may want to try a slightly stronger feeding next time. If the plant looks slightly pale but otherwise okay, that's a sign you're probably underfeeding. Again, increase the feeding rate but not drastically. If you see any leaf tip burning, that's the universal sign of overfeeding. Cut back the feeding rate significantly.
Slow to increase, quick to decrease. That's the mantra. It's always much easier to fix underfeeding than overfeeding.
That said, as far as specific advice on Fox Farms goes... I was never very fond of their products in hydroponic systems. They do okay in soil, but they gave me nothing but trouble in DWC and I quit using them.
