Powder vs liquid hardener on a big slab last month

Ran a 4,000 sq ft warehouse floor in Tacoma and used powder hardener on half, liquid on the other just to compare. The powder gave a way more even color and didn't leave those dark blotches near the joints like the liquid did. Anyone else see a difference on bigger pours, or was it just my mix being off that day?

Yeah, I've seen the exact same thing on big floors, powder just spreads more predictable and the liquid likes to pool up weird no matter how careful you are with the mix. I'd chalk that up to the method, not your mix, especially on a pour that size.
