How late into flower do you use molasses?

I've got some plants at 8.5 weeks into flower and I've been watering with no nutrients for 2 weeks now, except for molasses once a week (1 tablespoon per gallon). I'm planning on giving them another 1.5 weeks (at least . . sigh) to grow, how long into it should I continue to give them molasses? Thanks!

Im no expert....but id say stop it when you start to flush....

two weeks prior to harvest is when you should stop all molasses. when you start to flush, you should stop. now is when you just want fresh water to flush all that stuff away.

Thanks - it's already been a week since I last used it, and it looks like I won't be using again! That should make for about 3 weeks of flush prior to harvest - YUM!
