I have all the classic signs of thrips. black spots that rub off (poop), small silver lines on leaves, ect. how can I get rid of them. any of you guys have experience with these please let me know. I have 4 plants in coco and 2 in bubble buckets, all different strains. I have to get rid of them fast because one of my plants is looking much, much worse than the others showing signs.
here is a pic of the black stuff I keep finding. I haven't seen any bugs but this black stuff keeps showing up on the fan leaves. I'm pretty sure its thrip poop
