I’d recommend neither. Adding sugar, whether it comes from honey, molasses or pure sugar to your nutrient mix or to your soil doesn’t add sugar to your plant. The sugar molecule is too big to be absorbed by the plant through its roots by osmosis. In soil, the beneficial microbes might be able to convert it to something the plant can use but it is more likely to increase the amount of pests (bugs and bad microbes) and cause more harm than good. Starving the plant of nutrients the last two weeks does do some good, by feeding only water the last couple of weeks, you force the plant to live off its reserves and reduce the amount of chlorophyll and nutrients in its tissues, this of course leads to a better cure and smoother smoke in the end.
