First Layer Frustration/Calibration Settings
So I am getting very frustrated with this thing. I have a MK3S+ and cannot get a solid first layer. I changed out my hotend to a new one due to a clog and could not get it clean. I bought a completely assembled hotend with nozzle ready to go. Even bought some bowden tube from Prusa as well so it is all original. I cannot get the thing to get a good first layer. I start with the first layer calibration and adjust it to where it is not sticking. Usually around -1 or so but once it gets to the flag, the entire flag does not print and it balls up on the nozzle. HELP! Am I to high or too low? The strands seem to print ok but once it gets to the flag it just balls up. I adjusted it down to -1.6 and got a decent flag but the edges were still rolling up. I feel like this thing is getting very low. I am using prusament pla galaxy silver to set it with. I have resurfaced my smooth steel sheet per prusa instructions as well and still no luck. Yes I clean between each printing with IPA 91% and a paper towel as well. 
RE: First Layer Frustration/Calibration Settings
Have you cleaned the plate with washing up liquid (dish soap) and the rough/scratchy part of a washing up sponge? Then once dried and back on the printer use 99% IPA & kitchen towel. That solved a lot of adhesion problems for me. Once that was done I just kept doing the Live adjust-z calibration until I got it as good as I could get, then printed a large flat object just to tweak the live adjust -z until perfect, then aborted the print. The only other thing I did was switch on the 7 x 7 mesh bed levelling, yes it takes longer but it is worth it.
Your first is too high, the second and fourth about right 'though they could probably go a fraction lower and the third started too low and finished too high.
@3delight is right to question the print surface, there are visible smears and fingerprints, IPA is OK for cleaning between prints as long as you handle it by the edges only but when it fails use dishwashing detergent (Dawn/Fairy) and plenty of HOT water.
What has happened to the print sheet? It is scratched ... it shouldn't affect adhesion but it might impair the print surface; have you tried the other side?
And there are signs that your filament is damp, this might cause problems later in the print.
Cheerio,

How can you tell that the filament is damp?
Also the 4th picture is what happened after the z was set so I am confused as to why it is pulling up from the edge.
I will wash with the dawn and rinse really well. I will also get some 600 grit sandpaper and sand lightly as well. Thanks for all your help

Those whispy ends to the strings are typical.

That looks like a fingerprint pattern - there are other prints visible in the same picture.

Good.

What are you sanding? Don't spoil your printing surface.

It's too high. It should looks like a smashed potato, not super round like yours.
I have 1st layer at -1.550. A zip tie height, as an assembly guide suggested, is way too high.

Did you get this working?
A few observations:
In the first photo the filament is too rounded - the Z is too high. It should be much flatter.
Another critical item which you don' mention is A) the filament brand and type and B) the temperature. Different filaments (e.g. translucent) and different brands have different printing characteristics. If you have (preferably new) Prusament filament then start with that. Also a too-cool temperature (even by 5 degrees) can cause first layer issues like yours. I had a Prusament PETG print that for some reason the Prusa slicer selected 5F under the minimum temperature (which I didn't notice at first) and for the first time in years I couldn't get the first layer down...an extra 5F made all the difference and fixed it.
And for goodness sake do not take any type of sandpaper to your bed! The ONLY thing you need to use to clean the bed is isopropyl alcohol for PLA; for PETG it is recommended to use Windex (or something similar).
With good filament and proper temperature running the 1st layer calibration is all you should need to do. My 3S first layer Z is set to about -750 but every printer will be different.
