Will a herm take longer to flower???

My plant started developing seeds during the seventh week of flowering because I think I did something to stress the plant,anyways I am now into the 8th week and the strain calls for 8-9 weeks,could I expect a longer flowering time because of this??

Same thing is happening to me. I have 9 plans (2-fem bubbalicious 3-femwhite widow 1-pineapple express clone 3-Afghan skunk clones) I just found some herm nut sacks on one of the white widows, pinched them off. After checking them all out most of the others appear to have some seeds in the buds growing but the nugs are huge and covered in crystals so idk, i guess ill just wait 1-2 weeks and cut them down cause there is still lots of bud.. Herms suck tho! BTW i have an aero nft system on a 15 gallon resivior with all adanced nutrients + connoisseur, under 2 air cooled 600 watters. Started them in flower MARCH 7
