To answer the question, under most cases its impossible to specifically identify a strain based on looking at the plant.
Someone who is very experienced can sometimes make a good educated guess about the identity of *some* strains with particular characteristics, but that's about it.
If you happen to be growing one of the "classic" strains and an expert can see it *in person* they might be able to identify it.
A super connoisseur might be able to smell the finished buds and tell you something.
With respect to your plant, I simply don't think there is any way anyone can precisely identify the strain based on those pictures.
Your best bet of figuring out what it is is to start with where you got the seeds and work backwards from there. Who did you buy it from, where did they get it, and so forth. The likelihood of you correctly identifying the strain that way is still probably low, but its not zero.
If it was seedy commercial stuff, then what you probably have is Mexican grown stuff, sometimes called "schwagg" or "brickweed". Right now most of those are hybridized "mutt" strains, though they still can be quite good if grown right.
Lastly, as a constructive criticism, your plant is showing a lot of stem, and not a lot of leaf. That means its getting inadequate light and is stretching. Try using either more light, bringing the lights you have closer to the plant, or both.
