Leafzone is not a comprehensive fertilizer. I would look into something else or something that could be dosed along with it that fills in the gaps.

Nitrates should not be zero unless you have an aqua soil. Even then, you still need nutrients in the water.

api leafzone is a good iron supplement, but it lacks most everything else plants need. id suggest switching to something like easy green, or any other all in one type fertilizer to get more of the nutrients the plants needs. nothing wrong with leafzone, i still use it to supplement other ferts, but it really is not a good stand alone product.
