For the weights bp might be alittle small. Not sure on the corns i never kept any of my babies and grew them up. So i dont know about how fast they grow. The bp as long as it doesnt look really skinny should be fine. Some grow faster than others. I have an 07 pastel thats 235g he was born on 6/25/07. Hes not much older than yours. He on rats. Maybe you should try switching over to small rat fuzzys if it will take them. Again if it doesnt look all skinny. Then most likely just fine.
