this was a great thread i searched for foliar feeding and this came up... but all the general info pertaining to it i already knew... i have a question that i cant seem to see anything about...

my question if you can call it that is the effects of the feed being left behind on the plant??? obviously the plant doesnt absorb all of it, so some is left behind on the leaves. my problem is if i made a guano tea and used that to feed would i be smoking bat shit??? hahah especially if it was used in the flowering stage... does anyone have any info about the effects of smoking foliar feed buds and or any info about what may be left behind??? once i get started with things i want to foliar feed but i also dont want to ne smoking nutes and bat crap hahah

im guessing the best thing (for me) is to use it during the veg stage and then really wet the leaves down with plain water before they start budding
