Yeah, I use molasses once a week during the entire grow (after the second week) and then use it with every watering during a 7-10 day flush right at the end. Works well, and everyone likes how smooth and sweet the bud is once its cured. GWE has a tutorial on using molasses_ I think they recommend 1-2 tablespoons per gallon_ but you better check that, I'm not certain. Thats what I use 1x/week with a PH water and microbes_ don't mix any nutrients into this application since I use it to flush any salt buildup. Seems to work well with a coco/perlite mix that drains well and fast.
