There is some evidence of sugar increasing yield in corn.

Sucrose produced the best yield. However, they determined it was not practical to use in a large agricultural setting because it settles out in the highly concentrated nute tanks.
So they studied sugars that would be compatible with high EC nute tanks. Dextrose was the best, but less effective than sucrose. All the sugars they tested increased yield compared to using none.

It has also been shown that plant roots can uptake sugar which can produce a slightly sweeter end product. A lot of weed people don't want to believe that. But it's true. There is a dispensary near me that sells Ice Cream Cake that is literally like smoking cake frosting because it's so sweet. Not sure how they get it that sweet. My sugar addition appears to add a little sweetness which enhances flavor a bit. But I wouldn't call my weed sweet like that dipos ICC.
Anyway, I will continue to use raw cane sugar in bloom.
