whats the difference?

ok i just went on a month long vacation and asked my friend to take care of my plants for the while i was gone. When i got back they were all nice and older but i forgot to label the plants while i was gone so i have no idea which is which. I was growing 3 white widows and 2 deepchunk x hashplant (magnum) so can someone explain to me the difference? *sorry no photos camera is broken, thanks

Well, since you have 3 of one strain and 2 of another, can't you tell which 3 look alike and which 2 look alike? Maybe it'll be more obvious when they're budding
