So it's not bitter enough? It can be a tough style. My water is not well-suited to it so I often dilute with distilled and then you have the concept that softer water can mute hops so you feel like you have to dial it up and add more hops to make up for it. Then there are those who say that the Czechs (and Germans for that matter) don't add hops late in the boil. The Czechs might boil for 90-120 minutes and the last hop addition will be with 60 minutes or maybe 30 minutes left. I have tasted homebrewer's versions where they see that they need quite a bit of hops because of the soft water but they don't take that into consideration WRT their own water (which might be hard) and the beer turns out super hoppy and coarse. Lots of variables but I'm a big believer in allowing a lager to age a bit too so fingers crossed. Na zdraví!
