Clones should be taken in the Veg stage.....If you uve taken cuttings in the flower'in period once the clone roots it 'll asume it still at the same stage so you need to clone and let your clones grow a while,,,Doing it in a rush cant be good but .By the way how big is this clone?.
if its only had 24's light for a few days Stress is all i can think which can affect flowering but like someone said your plant your trip....Best of luck...
