I have been growing a few orange trees from seed for the past year. Most of them are growing fine, but a few months ago one of them began developing patches of orange-brown bark/scarring tissue (?) at all the branch points that looks different to the young bark at the base of the plant. The main branch hasn't grown since and the few new leaves that have tried to grow are a very pale yellow-green and misformed. Does anyone know what's causing this / is it a genetic thing?

Hello and welcome to the Forum.
Those look like a type of scale insect, though the focus is a bit soft. Gently scrape them off the stem with a fingernail or toothpick. If they turn into a gooey mess, they are scale. If so, continue to scrape of all you can find, and then spray the plant with a horticultural oil or soap.
