That is a very real possibility nossaHeads. Also there is a chance it some insect. They stop by and take a bite out of one of the leaves. Makes a hole by biting. Then deciding they do not like what they are eating they leave. Well the plant has a small hole to deal with so the edges of the bite will turn brown and dry out to keep nutrients inside. Next while the leaf is fighting for life. The area around the bite will use up different nutrients and change color. Most insects secrete some natural chemical that may affect the leaf too. First is to flush with 3 times the water just in case.

Next try one of these pest & insect controls

My favorite
Hot Pepper Wax - Targets most garden pests including aphids, spider mites, thrips, whitefly, scale, and many others. Simply mix with water and spray. Pests will stay away from your fruit and vegetable crops. The Ready-To-Use comes in a 22 oz spray bottle. The concentrate comes in a 16 oz. container and makes 2 gallons of spray. Made from hot Cayenne Peppers.

This is from the company's marketing material but they do work and are all safe to use around a resin producing plant.
