My newly finished pool was filled about 12 days ago. Initially, the PB dumped chemicals and after a few days, the water was clear. Now, they have provided quick orientation and I am truly on my own. My water turned cloudy :). Below are results from tests taken this morning:

FC: 0.0
pH: 7.2
TA: 90
CH: 400
CYA: 50

I believe I need to add Chlorine or what should I do first? TIA.

Nice signature. You do have a good test kit.
Did you test for Combined Chlorine?
You need to add some chlorine and keep it in the proper range asap FC/CYA Chart
You do have a new pool so be cautious going forward to avoid damage.
Sit tight there will be more good folks here to help.

I have the TF-100 test kit. The CC test was 0.0. I have 2gal of 10% bleach which I am about to add. Can someone tell me how much to add?

Pool math said to reach FC target of 6 with current CYA at 50, I need 87oz of 10% liquid bleach, is it correct?

Let's take a closer look here.
I am not so sure a SLAM is in order or is wise given the new pool.
Do not SLAM (or shock) the pool during the first 30 days. (from here) Start-up New Plaster - Trouble Free Pool
Two things we know, zero FC and CC also the water is cloudy. Cloudy water could be from plaster dust or the high calcium hardness correct?
A zero FC is not good, so raise it for now to 8ppm with the 10% liquid chlorine and test the FC and CC levels after an hour.

OK, thanks to all. I will not SLAM the pool but will only add liquid chlorine (10%) to the pool and take readings again in the evening.

FYI. I added 1 gal of 10% liquid chlorine in the afternoon. Water looks clearer but not crystal clear, hopefully it will improve overnight. Below are readings taken before bed time.

Below are FC and CC results of water sample taken at 7:30AM. Compare to results taken the evening before, the FC dropped .5 and CC went from .5 to 0 using DPD test. Is my water OK?

Rest easy.
The overnight free chlorine loss of 0.5 ppm and CC of less than 1 indicates you do not have an organic contamination issue. Your cloudy water is probably an issue with your recently plastered pool.

Yes, your free chlorine needs to be more than zero. I use the TFP’s CYA/chlorine chart to find my ideal target free chlorine-i
And since your calcium already at 400ppm, you might want to use liquid chlorine and stay clear of di - chlor (will raise CYA, and calcium hypo (will raise calcium hardness)
