You can't get 6-3-12 or the OP's 6-2-12 with just those two ingredients because the ratio N/P = 18/10 = 1.8 is fixed whereas you want N/P = 6/3 = 2.0 and the OP wants N/P = 6/2 = 3.
But suppose you also add urea 46-0-0 as follows:
2.67% (46-0-0)
61.47% (18-10-5)
35.86% (0-0-60)
That combination would be 12.3 - 6.15 - 24.6 which is in the ratios, 2:1:4 that you want, although more concentrated.
