Need help identifying this

[Nvykos (Sam)]

I’m unsure what this is, little white maybe flowers but no idea. Haven’t seen this yet with any grows.

Only on one of four identical plants.

I’d say spider mites but could be wrong: check with magnifier

@Nvykos What cultivar is that and how old?

[SlingShot]

time for a little neem oil spray. Tops and bottoms of all leaves.
