Yes water and buds do not mix... Vpd being relative to growth "green zone" is good but misting your buds could lend itself to all sort of problems.. Do not do this.. Cleaning buds is one thing... Spraying your plants with water and allowing the water to "sit" is something different. Mold is too much of a concern to even consider spraying in bud stage... I don't spray... I have access to foliar sprays I have no desire to really spray plants... There is not a whole lot of trade off really... The minor increase in growth vs. Not being aware of symptoms as they progress.. Yes foliar spraying can "hide" problems... And doing bad foliar work is "devastating" to a plant so..
