Indoor Generic time seed to harvest

I am planning a continuous grow under 1 light. I will be running various autos. I will be using lst.
Is 12 weeks from sprout to harvest a good generic timeline for planning?
Im thinking starting 1 plant every 2 weeks. But thatd be EXTREMELY reliant on everything following that 12 week line almost perfect as my tent wont hold 6 flowering plants.
Im ok with it being just a little early or just a little late. I guess the real question...

Would the pros/experienced consider the 12th week of MOST autos within the harvest window?

I know genetics and phenos wil vary... Thats why i am asking for a very generalized answer. Yes or no... And what week if not would be best to plan? Thanks in advance

committing 1 crime to avoid commiting multiple crimes... is it ethical? is it moral?

with 1 seed every 2 weeks could end up with 5/6 bottles of feed,and we know what stoners are like im liking the sound of 2 seeds every 3 weeks or 21 days whichever is soonest

Shoulda mentioned im 100% organic and dry amendments. I do water only until stretch then bloom nutes. No veg nutes since i reamend the soil with them. So i can kinda get away with a generic topdress bloom mix every couple weeks.
