yes you ca n flower the plant, they look like clones? the internodes are spaced alternatively like a mature plant so it will be ok. whether you get 2oz of the plants is another matter and will depend upon a whole lot of variables like strain, vege time, pot size, nutes fed or not fed, availability of oxygen and co2, light ...MORE LUMENS = BIGGER BUDS, and so on. good luck anyway.
it is a clone yes my friend who gave me it says it will get 3x bigger in flower he said i should get 3 4 of each if i did it right 250 w in a 2m tall 1.25 length tent
