Hello, I've got a very healthy plant, however I can't figure out what these white specs are. I'm growing in a hempy bucket, and the fan is very close, I assumed it was perlite dust. Bow the plant is way above the perlite and I find it unlikely that's what it is. I've put lady bugs as well as captain jacks dead bug about a week ago and I still see new white pebbles at the top. Other than this problem she's very healthy, about 4 weeks old from clone. They are very tiny, and like like white specs on the leaf. I look under a microscope but don't see any movement. Any advice?
