the plants look good man, if they are all cuts from the same mother though they should all be the same pheno, you get different phenos with plants from seed. i did look at the link and they did not look to stretched to me they were kinda but not to bad. it could just be the strain. most plants will double to triple in size once it is put into flower this means an 8 inch plant when placed into flower will grow to be 16 to 24 inches if not taller. they look fine to me and not to stretchy.
the cfls in the veg cab look like they could be closer to the plants, and aslo what is a GWS, great white shark i assume and if so this plant would not of made the others stretch unless it shaded them out
