PH really needs to checked first.
Unless I know your PH I won't know what your deficiencies are, what's causing them, etc..

If your PH is too low or too high, Ca and Mg could be present in the soil, but the plant is unable to use them. Then by adding nutrients, you can create a situation where you have too many nutes which can cause nute burn, lock out other nutes, etc..

It's not worth the additional headaches that can potentially be created by guessing the solution to the problem.
