Does anyone know why a plant does this, is a build up of something? I've only noticed it on 1 plant might have 1 more like that a different strain though

Its just nice strong knuckles likely from a fan blowing on it and strengthening the nodes........or its the Dew. Do you have a strong fan blowing on it 24/7? Nothing to worry about though.

Cellulose "knuckles". On some of my strians the lumps from main branches onto secondary branches can double mass when adding a low but steady dose of potassium silicate to the main base feed. Ive noticed it with and without silica and its definitely bigger on the silica fed plants.
