You may want to be careful with using rare candies. Using too many can cause your pokemon to be really weak for its level due to not gaining IVs when leveled via rare candy. Using 7 rare candies is treading dangerous waters imo.
Pokemon can't gain ivs. These are determined when the game generates the pokemon and can't be changed. They only gain evs when battling, and these can be reset and added in super training. Using rare candies is perfectly safe now. Go ahead and use them.
