Hi Russel,
Thanks for reaching out!
Unfortunately Event Tickets Plus does not currently support recurring events. You can technically add the tickets to them, but it will be the same ticket on all of the events, which is why you were running into the issue with the global stock.
A workaround for you might be to create single events, use a post duplicator plugin like this one to copy the event, and then add on the tickets to each event (saving custom fieldsets that you can use on multiple tickets could help you save a little time here).
I’m sorry I don’t have a better answer for you…If there’s anything else I can do to help you work this out, please let me know.
Thanks,
Jennifer
