Wanting to increase weight of buds

It's done when it's done, chief. You have two options: Suck it up and wait it out, or take it early with greatly diminished results.
If you want to increase weight you need greater light intensity, and longer veg. time (with increased root space). Those are the two determining factors. Studies that involved decreasing light to less than 12hrs. have pretty much universally ended with decreased yield.

use fox farm cha ching go to your local hydro store and get sum but yes molasses will work too

To get harder, heavier buds you can start with climate modification. Decrease temps, increase watts. Canopy management is essential to spread out plants evenly and get penetration. Sea kelp, molasses, and shooting powder will put on some weight and density.
