I agree with crazyhorse. Remember, plants grow on their own, nutes just HELP. The reason I say this---this way---is cuz some seem to think ya have to feed with every watering. Then the post "whats wrong with my plants?" The answer is often --you guessed it---nute burn! For most soil grows, its my OPINION that a feed of once a week is sufficient unless you find yourself deficient in a particular nutrient.

Keep in mind there are waaaay more experienced growers on here than me. But personally, I stick to once a week in soil, unless my plant tell me they need more of something. Good Luck
