I soak my plants with NoShock when I transplant and I dont get the growth stutter. I think any weak vitamin b would do the same thing, plus it keeps the root ball from falling apart.
Plants need to be watered when you feel the weight difference. They need to dry a little because the roots need oxygen. You may have dry pockets it people say they look dry. Break up the soil a little, make sure your are getting a good soakin all the way through, and let them dry out all the way before you water again.
How big are your pots?
