What it looks like
Silvery or bronze dry patches and squiggly streaks on the tops of leaves where thrips have scraped the surface and drunk the sap — often with tiny black dots (droppings). The pests are slender, pale-to-dark, and dart away fast when disturbed.
Symptoms
- Silver/bronze streaks and stippling on leaf tops
- Tiny black fecal specks
- Slim, fast-moving insects on leaves
- Distorted, weakened new growth in bad cases
Causes
- Introduced on new plants or clones
- Open tent / drawn in from outdoor plants
- Warm, dry conditions that speed their cycle
How to fix it
- 1Isolate the plant and knock adults down with a spray (insecticidal soap, spinosad, or neem in veg — never on flowering buds)
- 2Blue sticky traps (thrips prefer blue) to monitor and reduce adults
- 3Predatory mites (e.g. Amblyseius) for a standing biological control
- 4Repeat treatments every few days to catch newly hatched thrips
Prevention
- Quarantine and inspect new plants/clones
- Sticky traps as an early-warning net
- Keep the canopy clean and airflow steady

Silvery thrip streaks get mistaken for mite stippling or light bleach. Satoru weighs the pattern against your light distance and history to separate a pest from an environmental burn.
