Mutant? Or super early Nanners? Should I pull it?

[SkullFace]

RQS Sherbet Queen auto. Planted 16th Dec.
Medium: Soil/perlite
ph: 6.5
ppd: 205
Water around 250ml every 2 days.
Temp: 24c/75f
RH: 58%
Light is 20inch above plants MH TS600 *checked the lux etc and seems good*

Is this a mutation? Nanners? sickness? Its my first grow and I don't want it to mess up my second plant *which is about 4 times the size and doing great*.
Should I just pull it?

Somebody suggested it might be Whorled Phyllotaxy?

Any help is appreciated.

Looks a bit mutation to me.
