Yeah it happens to me too sometimes . What does the diatomaceous earth do for veging plants ?I sometimes get numb lips after smoking...before you say laced i grow my own indoor organically and dont use pesticides or sprays...i use demetrious earth during veg in soil..if its the tar/resin maby its worth looking into as a topical solution for minor surface pain..
Oh . Good to know . I use fox farm soil and that goes hand in hand with gnats . I have that stuff for my dogs . Helps combat and keep fleas away didn’t know it had good plant use .It kills pest but its just fossilized algae...its like broken glass for bugs but harmless to people an animals.
