my nails keep chipping

My nails keep chipping

I do my own nails on top of my real nails. so i grow my nails out and put acrylic over them. everything i use is valentino. well after i put the acrylic , i file my nails down with the rougher grit and then i use a beetles base coat and cure for 60 sec. i apply the white and then cure for 90 sec. 60 + 30 sec. then i apple the red and green and cure for 60. then top coat and cure for 90 sec again. this is my second day of them and they’re already chipping. i don’t miss any spots when i apply the top coat and even apply it a little bit under my nails so it doesn’t chip.
