Sorry I've taken so long to reply.
There is information on harvesting Hibiscus sabdariffa at
If you look at the image on the following site (near the bottom of the
page), you will see how large the calyces become. This image shows the size
of the calyces before picking. I guess you would just have to try a few and
when you can snap them off, they are ready. If you can't snap them off and
need to cut them, then they are really a bit past their best but are still
fine for making drinks etc. I find if I leave them too long that bugs start
to damage the calyx and then the calyces become useless.
Best wishes with your crop
