Odd yellowing on leaf

[UrbanGardner]

I was wondering if anyone has ever seen anything like this before? There is a single leaf on my plant that looks as if I spilled bleach on it. The strain is Strawberry OG and is about 10 weeks old and about 4 weeks into flowering. I first noticed the yellow spot about week 5 or 6. The plant including the leaf with the spot is perfectly healthy. No deficiencies detected anywhere. I use dry organic fertilizer so there is no chance of me spilling on the plant. I was wondering if this is a genetic anomaly?? I look forward to any feedback on this one.

Variegation- It is just a genetic anomaly- nothing to worry about.
Plant looks very good, btw...

Thanks. I had to google that one. I had a feeling it was an genetic anomaly but couldn't put a name on it.

For folks like me:

What causes variegation?
Caused by a genetic mutation, In this type of variegation, plants show two different chromosomal make-ups in a single plant, where some tissue is able to produce chlorophyll and other is not. The result is a plant with white or yellow zones intermixed with the solid green form — this kind of plant is called a chimera.
