Who uses Fluval stratum for their rare plants?

I’ve started using the fluval stratum on my baby plants, rehabs, cuttings, etc, and they’re growing very well! Overall the maintenance seems low which I like! I’m considering switching some of my larger potted plants that are in super chunky aroid mixes to pure stratum, or a stratum mix. The issues I’m having with my chunky soil are balance issues with the nutrients. Has anyone gone to using straight fluval?? Any advice?
