You don't use Sweet with molasses you use products like Sweet & carb load instead of molasses.

This is what they say about Sweet.
"During the vegetative phase, application of Sweetâ?˘ prevents plants from becoming leggy and soft-stemmed in the presence of high nitrogen concentrations. At the onset of flowering application of Sweetâ?˘ ensures a seamless and stress-free transition from the vegetative to the flowering stage even though nitrogen levels are artificially kept low. The key ingredients present in Sweetâ?˘ are rapidly taken up by plants and utilized for the biosynthesis of crucial compounds to maintain optimal metabolism. The continued application of Sweetâ?˘ during the flowering and fruiting stages helps maintain a proper balance between photosynthesis and respiration. This is significant because, during flowering, many growers use high carbon dioxide concentrations, high temperatures and light with longer wavelengths. Under such conditions, respiration can outstrip photosynthesis causing excessive ethylene production which results in senescence, yellowing of leaves and leggy growth. Sweetâ?˘ protects plants from this metabolic imbalance and helps produce sturdy stems with short internodes and an abundance of buds, flowers and fruits."

You can find it at Hydroponics stores and eBay too. This is something that HD does not have or even most garden centers carry either. It's a speciality product.

There is another one called Carb Load that I personaly think work better to pack on more weight.
