Now its time for flowering so from 18 hours on i reduced to 14 on 10 off and she turn flowering so will leave her with 14/10. At first i always reduce light 14/10 some indica plants can flower with 14/10 so i always give a try first if plant move to flowering i leave 14/10 if after 15 days i dont see any sign of pre flower than go for 12/12.
