AND I grew this! and this too!

My first carrot and what may be my entire crop of shelling peas. I'm going to have to use that ounce of peas for something really special! In other news... I think I might have blossom end rot on some tomatoes. I don't know what that is yet but the butts of my first few tomatoes are black and rot-ty looking. I guess I'll have to look it up. Any words of advice? 99.9% of my toms are still green so maybe there is something I can do...
