On the lower surface of leaf, pinkish coloration of structure ,predominant in maximum plants are found.Is it normal or any pathological signs??The plant is Prickly chaff flower/Apamarg(Achyranthes spp.)
Feeding damage from Leafhopper nymphs (Norvellina sp.) can look similar but is more of a pink welt whereas these galls should be crystalline and actually reflect a little light.
