What to put down at 5 weeks into new lawn

I overseeded a 13,000 s.f. troubled lawn and applied 10,000 s.f. of fresh seed. I applied the usual starter fertilizer at the time of seed and I would like to know what I should put down now, 5 weeks post application? Location is Southern New England.

I am applying two applications of starter fertilizer on new lawns about 60 days after the first. This late in the year you might go with a winterizer fertilizer for root growth. I would shy away from the high nitrogen #'s till next year. Have you had a soil analysis recently? That could provide some useful input as to what you really need.

Can you comment on the grass, color, good bad germination, density?

I've reapplied the starter fertilizer after the grass has started to grow. I have seen great results doing this, really makes it take off.
