Pothos has white grainy gravel-like stuff on underside of leaves

Question

My Pothos has white grainy gravel-like exudate on the underside of the leaves. Is this something I need to be concerned about? The plant looks healthy but the underpart of the leaves looks as if someone splashed milk on the underside of the leaves.

Answer 1

Without seeing the substance I would be on the cautious side and treat with Neem Oil.
Neem Oil works as both an insecticide and fungicide and is safe for people and pets.

If this is a newly purchased plant it is likely it is a residue from watering, fertilizer and pest control from the greenhouse grower.
It could be just wiped away with a damp, soft cloth.
