Fox Farms is DEFINETLY for soil, they have a hydro version of there grow formula but the original big bud and grow big are for soil. I think fox farms is borring personally, really the pura vida nutes are the shit for a base nute, they have a high consentrate I have had nothing but good results from it, Yellowing leafs can be anything, but just make sure not to overwater your plants, stick ur finger in the soil and if its even alittle wet wait a day, this in turn will get rid of the gnat problem I am assuming your probly have, also never over do it on the nutes, I always start with 1/4th streght of all my nute mixes then gradually go up in power, if i see something different after a watering i back off alittle. let me know if you got more questions.. +reps never hurts ha

I would really try keeping the ppm levels at no higher than 1000 during flowering
