Here is a pic of my best fan leaf which hasn't quite reached full maturity. The mature leaves are a very dark green.

The friend who gave me the seeds and is yet to see my plant, thought that they were silver pearl but now is not sure because they might have got mixed up with some pure indica.

I've found some good strain descriptions at the Goldenseed site and have narrowed her down to 3 possible strains in order of preference; Aphgani #1, Northern Lights or Silver Pearl.

The broad leaf width and overlap along with the very dark green they turn, leans me towards Aphgani #1, but any help would be appreciated.

All 3 strains you list have indica lineage...so it's hard to say/tell. The leaves on the tops may also narrow a bit as the buds form.

right now I'd guess Afghani...that leaf/the structure of your plant looks alot like a Bubba Kush I have.

good luck

Here is a site I found which has pictures of the fan leaves from some of the main strains which helps in the identification of the strain.
