Did you Know Molasses is bad for plants ? Good thing cannabis is a weed (true fact) Molasses is good from the start it creates its own microbes and Helps protect the soil and keep a healthy plant. I don't know about it enhancing buds in late flowering but if you are on week 5 I would ad a tsp to every other watering between feedings if you have a good strain flavor won't be a issue
good luck
