thats really small to be over a month old, i mean im only in my second grow, but mines were bigger than that at 2 weeks, and yeah i agree they need to eat bad look like their starving lol, but feed them and throw them under a light (bout 2 to 3 inches away) just to boost up the growth a lil bit because thats really tiny, looks about a week old. . . just my lil 0.02 their to young to tell the strain because all strains grow about the same so give them time and some tlc they will let you know everything you want to know. . . gl an hg
