Classic Thrips Infestation

Tiny pests (need magnifier). Mottling on new growth is telltale. Spray topical (pyrethrin/Neem) or systemic insecticide—coat all surfaces. Repeat in 5–7 days (topical) or 30 days (systemic). Follow label. Damage is permanent; wait for clean new growth.

Watch insecticide video.

Good growing!
