"Please don't foliage feed, foliage feeding can trap nutes and moisture in the bud this late into flowering. You'll run the risk of mold or if not your going to taste once smoked. Just my 2cents."
The possibility of mold is very real.........gotten be careful is all
I foliar feed every plant up till harvest, taste great..and extra moisture only helps give a slower dry..I'm sure you also flush your weed? Learn how plants uptake nutrients and what happens to them afterwords before criticizing...
Its perfectly fine to foliar feed..I wouldn't chop immediately after but by the next morning the plant will have absorbed or sweated it off
