  You have something wrong.  ALL wiring to the hot tub must be on a GFI breaker.  Why would there be a 30 Amp breaker in the sub-panel ?  Does your tub only require a 20 amp circuit ?  Is this a 120 VAC or 240 VAC circuit ? What guage wiring are you using and what is horse power of your pump and wattage of your heater ?  If you can't answer these questions, hire an electrician.

Go here - http://www.hotspring.com/sites/default/files/pdfs/owners-manual/hot-spring_spas_owners_manual_2010.pdf (http://www.hotspring.com/sites/default/files/pdfs/owners-manual/hot-spring_spas_owners_manual_2010.pdf)

And see the factory wiring diagram. Your tub DOES indeed need a sub panel with TWO breakers:

One 20A and one 30A. They usually install GFI breakers at the sub panel and a regular breaker to feed the sub from your main panel. That's for a reason: if the heater develops a ground fault, only the breaker feeding it will trip and the tub can continue to circulate water as needed.

From a safety standpoint, I don't see a difference in running the GFI at the panel or in the sub - but that is assuming all requirements of the NEC are complied with.

  So if I put regular 20 amp & 30 amp breaker in sub panel,& 50 amp gfi breaker in main panel in house thats ok.Because we will only have tub in use during warm monthes.During winter it will be drained.So if something happens to heater or pumps it will just trip main breaker in house?

True - any fault will trip the 50A at the house.
