What am i growing!?!?!

I have 2 plants and as you can see they are totally different in colour!
I recieved them as clones and not sure what strain, any ideas as to why they are so different in colour, I treat them both the same.
Is this normal or do you think I may be doing something wrong?

????anyone????

have u got them on 112/12 yet?

maybe root problem's but i dont kow sorry.

Hey mate.

I have switched them to 12/12 tonight after taking 2 cuttings about 1 hour ago. Pictures were takin before cuts.

SOG, Switched on Gardener reckons (without seeing pictures) one is sativa the other indica so that is the difference in colour.
