@FoTwenny,
Thrips if left untreated can poison the plant and in turn harm you!
Signs are white specks on leaves and can look like a calcium deficiency.
You can spot them with the naked eye..
Young are white and the older they get there more brown in colour.
Little f*ckers like to hide in the veins of leaves so can be tricky to spot!
Google them its quite interesting 🤓
