Nah, don't use molasses... Just a big sticky mess...and will attract every bug around... Use nutes that are high in Phosphorous and low in Nitrogen. Nitrogen is used mainly in the Vegetative stages, so if your plants get too much when flowering, you will have some real leafy harsh buds. Phosphorous is used by the plant to flower and maintain a healthy root system... I also suggest using "Superthrive" Its a mixture of 50 vitamins and hormones. It seems to make a difference...you can git it at your local MegaMart wally world type store. Or order it from the net.
