Let them dry out, they should recover themselves. Walmart sells a cheap moisture meter in the seasonal section if you want to be absolutely sure.
The problem with going from small pot to massive pot is that you are now watering mostly dirt. The plants roots arent even %10 of that mass right now, more water than it needs and takes longer to dry out.
It can be done but its tricky. I prefer to go in to 1gal from solo then in to my 3 gal when the plant gets bigger.
Now all you can do is wait and not water.
