PlantPalSpeckled leaves: check for spider mites
Tiny moving dots under the leaf are more telling than a web on its own.
What to check first
Look for many pale pinpricks, especially on leaves with fine webbing underneath. Tap a leaf gently over white paper and use a magnifier to look for moving dots.
What to do now
Separate the plant and check its neighbors. If its foliage can be washed, gently rinse both sides, especially underneath. Clean up the rinse water instead of letting it run into other pots.
What to watch next
Check the leaf undersides again in a few days. If moving mites or new speckling keep appearing, seek advice on a treatment suited to mites and that plant.
