Mollases Verses Mollases

Im in the 9th week of flowering w/ a 600hps and plenty of air. Ive just started to flush but with mollases first w/ water (1tbs. per gallon). SO.. Is this the right thing to do? I have 6ft. big bud w/ rockwoll in a 5 gallon bucket.
My question is : Can this increase Yield?
We will see

At this point they are not going to get bigger, you are using water and molasses for the last week to make a smoother smoke.
