We estimate the energy of the lowest charmonium and upsilon states with hybrid admixtures using the method of QCD Sum Rules. Our results show that the ฮจ (2S) and ฮฅ(3S) states both have about a 50% admixture of hybrid and meson components. From this we find explanations of both the famous ฯฯ puzzle f
