one of my first grow rooms was in an attic. my a/c wen out on a 100 degree day and my room reached temps around 130F.
my plants never did fully recover, growth rates were slow as hell from that point on.
Here is the thing: try not to stress your plants by making tons of changes while they are stressed.

seriously, water them and leave them alone. allow your grow medium to dry out before re-watering. Its the hardest thing to do right now, but its the best thing for your plants.
keep temps in control, and dont worry about nutes right now, your plants have plenty of food now that you replanted. they are too small for food, so avoid feeding until they are larger.

re-cap: leave them alone:thumbsup:

hope this helps
