    Magnesium deficiency!

    "Magnesium deficiency will exhibit a yellowing (which may turn brown) and interveinal chlorosis beginning in the older leaves. The older leaves will be the first to develop interveinal chlorosis.Starting at leaf margin or tip and progressing inward between the veins The leaves curl upwards."

    looks like Mg def, but why..............
    i think you did it. with the feeding. a "handful"...........a "little extra." you are at the root of this problem, imo.
