Hit those with fertilizer. I've had 3 out of four plants that I put in the ground all at the same time and had one not be ready. It's like I missed the cutoff hour or something for that last one to be ready. If you planted them in a clockwise/counterclockwise rotation then of course that theory isn't going to work, but there might also be the fact that the gardening site is rounding off to days and not hours. It's possible those other plants take more hours total but still fit within that 5 day period.
