Do we think it's safe to apply certainty to my newly established P77 lawn. We have had mid 90 to 100 degree temps. I have some spots that still need filling in. I wondered if I should go ahead and tackle this weed problem now?

What kind of weeds are you battling?
I'm sorry but from the picture I do not see a lot of weed pressure at all.
To blanket spray any herbicide would not be a good idea. You do not want to damage your lawn this year. Push growth. And only when you see extreme weed pressure do you broadcast spray during your first year of seeding. With all that said I did blanket spray. But I did also have extreme weed pressure and as a result I had winter kill the 1st year.

I have a ton of crabgrass, and several real heavy spots of sedge. I have a few spots here and there with clover. Here are a few pictures that might help give a better look.
I guess Tenacity would be the best crabgrass herbicide. @Tellycoleman after seeing the pictures do you still suggest to stay away from the herbicides? I thought mowing would help eliminate some weeds but I only have two cuts on the grass so it's too early to tell if that's going to make an impact.
@jakemauldin
How many days has it been since seed emergence? Have you cut the grass several times yet?
If you've cut at least three times, concerning the clover, three-way with MCPP or MCPA.
Get a paintbrush and start brushing the crabgrass with glyphosate or use Drive XL8 and expect some damage.
Regarding the sedges, if it's been a month since emergency, certainty should work fine.

@HungrySoutherner Thank you for the save, I read the label but was zoned in on what it treated and completely forgot to check that it was safe for Bermuda grasses before I posted.
@Movingshrub It will have been about 40days post emergence. I have two cuts on it, number 3 cut will be tomorrow. Sedge started out as the most prominent weed but I think crabgrass has taken the lead in growth. I have Certainty on the way. I have read some people that had success with Certainty about this stage of growth and others that are fearful it will damage/slow growth. I wasn't sure of the general consensus for Certainty. 2,4-D for clovers?

If you're battling crabgrass I would recommend Drive. Maybe some MSMA if you can get ahold of it but it's not labeled for residential use. For the sedges I would hand paint a sedge specific herbicide.
