If you know until which chapter he is certain age, then that works. Otherwise if the timeskip is around a year or less, "Age: 18-19 (Pre-Time Skip) break 19 (Post-Time Skip)" also work. Or if you know the chapters (for example): "Age: 18 (ch1-63) break 19 (ch64-chapter timeskip number) break 19 (Post-Time Skip)" can also work, or anything among those lines.
