Can you give a better description of what it's like now?
By chalky do you mean there's no colour pay-off, it's too hard, too crumbly, the colours have split, the colour intensity has gone, etc etc etc? If you give a better description you'll get better answers.
In the meantime give the blush another day or two to completely dry, then take some sticky tape and use it to tape-lift off the top layer of product. Try it again after that and see if there's any improvement.
