Upgrading PHP limits

I am currently trying to deploy Nextcloud to a kube cluster. I have been able to get it up and running with out a problem. The only issue I am having is that I am able to increase me upload limit from the 512mb on the Nginx but I can not figure out where I need to adjust the value to increase it on the PHP side of the helm chart.

I have deployed it with the base helm chart configuration and I have tried to adjust it in the phpConfig and the config section.

No matter what I adjust I still have a max value of 512mb for both of thy Memory Limit and my upload max size. I would like to increase this value to a couple of GB since I am working with video files. If any one could point to the correct section in the helm chart that I need to adjust I would greatly appreciate it.

Cheers,

Which Helm chart for which image?
