What soil is it in ?

What PH's are you running for your feed ?

What did you feed it ?

How big is it ?

How much water are you giving it ?

General rule of thumb is if its showing problems and its light green its under feeding and if its showing problems and its dark green its over feeding. Please bear in mind that PH massively affects nutrient uptake and it can have masses of nutrients in the soil but if the PH is incorrect or there is too much fert in there your plant cant absorb them.
