It starts to apply the moment your spell hit, and it ends 3 seconds after your last spell ended its influence on enemy champion.

Also its not 6 but 3 ticsks.

on Q alone its (like you can read on the middle of coments page 1):

4%+4%+4%=12% (that's the duration of Q alone), and then after the spell ended its 2%+2%+2% = 18% current HP.

On EQ

1st three seconds its 4%+4%+4% = 12% then you have one second of E alone (since E duration is 4 sec and Q is 3 sec) 12%+2%=14% and then you have 3 second of the passive alone 14% +2%+2%+2% = 20% from max HP on his every EQ combo... And now add the torment debuff and dmg from both spells.
