I am with scottsmith on this issue. First of all 10 gallons a week will do squat, but not much more. I use all my water and it is amazing how well it works. Even at that It is nowhere near enough and I must feed my citrus trees a very careful balance fertilizer. Any potted plant should be feed a balanced food. I don't know whether your plants are in ground. If your citrus is in ground it won't hurt but other plants will benefit more.
