changing your cycle beyond 12/12 is not recomended as the plant will revert back to veg i tried the 14/10 cycle and my buds died and the plants reverted, when i tried to put them back to 12/12 the yeild was very low and not heavy, the quality of the smoke was impaired aswell. The plants were taken from a known good mother, of which other plants did really well on the 12/12 cycle, but changing the flowering light cycle is the worst thing you can do.
