Maybe dying?

Maybe dying?

Ok, I have another question. I planted my tomatoes on Feb 15 from seed, then this past Saturday I planted them in 3" peat pots and set them all back in the bay window. I've been watering them and feeding them occasionally, so why are the tips of some of the leaves dried up? I don't understand this and I'm not sure how to fix it, if I can. Please help :/
