If you ph the water after you put the nutrients in the water, you will be able to follow the feeding schedule that Fox Farms recommends using the full lineup of liquid nutients. If you add the soluables only use 1/4 teaspoon per gallon along with the liquid nutes. I've been doing this for the last several grows without having any nute burn or problems caused by overfeeding. The last week to 10 days I stop the nutes and add black strap molasses at a rate of 1 tablespoon per gallon of water. This is what I do and the results I get may vary from what you get depending soil, growing condition and a host of other factors. The bottom line is you will have to experiment by varing the dosages until you get the desired results.
