Bell pepper plant
I have noticed groups of little white dots underneath the leaf. I have no clue as to what this is and what could be done about this. I have now removed the leaves infected, but I'm not sure how to prevent it from happening again. I've nod spotted any aphids. Please advise. Thanks!
