Not sure it's wise to mist plants at flowering stage, you stand the chance of bud rot, during veg ok I guess but I never do.
i will second this as i learned to spra/mist only in veg, DO NOT MIST IN FLOWER, theres multiple reasons as to the wetness can hold in the buds forming makin bud rot, or mildew/mold can appear after a lights out spray! you can foilar feed in veg all the way up to about 2 weeks in flower but once buds form and theres hairs i suggest dont do it at all, just water from the soil! my 2 cents for ya
