I just recently started reading forums like this and it seems most do 2 weeks before. We do 4 weeks here, we did compairsons back in the day and tended to like the results better with the extra time on plain water. The only real difference there was was in the taste. It's probly a matter of opinion though, i met one dude that swore on all the way to the end with his organic tea mix for pretty buds, best way to decide is try it out and see what your plants like.
molasses is to help up the crystals.
