I use regular sugar with my flush, on a regular basis. I do a half a cup as an amendment and water over it in the last 2 weeks of flush, I do this twice and alternate every other watering during flush I've found it adds to the flavor and smell as well as gives it a stickiness greater than not using it. I've also used agave nectar during flower and in flush before with similar results. I firmly believe that whatever you feed your plants goes directly into the plant, so giving them say molar would give them a underlying profile of molasses, and I hate the taste of molasses, so I used alternatives. I use coco/peat/perlite mix with Fox farm liquids and powders. It wouldn't hurt to try it, especially if you are flushing, just don't give it sugar and harvest water it down that's why I alternate. My joints burn clean and never run, strictly white ash, and always a great flavor.
