Really need help. I've searched both houseplants that I have and neither seem to have any pests on them or fungus. One of the plants has leaves curling up and a few leaves that have spots that look like something's been eating on it. The other plant doesn't have curling leaves, but has a few spots where it's been eaten on. I've sprayed with soapy water and rinsed. Searched leaves, stems, etc. and found nothing. Worried the most about the plant that has curling leaves. Seems to be spreading. Have had these plants for so long & don't want to lose them. I am posting photos of the curling leaves. Appreciate any help. Thanks.
