My suspicions might be right, but I could also be wrong.
Is this a new spike I see in one of my phals? It started out some weeks ago as just a green knob at the base of the plant, then this green shoot started growing late last week. Hoping for a new spike!
Yup, a root! You're probably disappointed, but roots are good. Roots and spikes can be easy to distinguish if you know what to look for. Root nubbins are are round with a rounded tip, and spike nubbins, are more flattened with a characteristic mitten shape.
