Don't increase the ppms just yet.... Wait for them to show solid signs of new foliage.... Once the new foliage is coming out, you know the roots are settling in nicely and they can handle a bit more.... They should be ok with 300-400 ppms for now....

What you want to pay closest attention to is the new growth.... If it starts to lighten up like lime green....you'll definitely need to increase ppms....

As long as you re member what you've given them and then see how they react....it'll be easier to identify problematic signs early on....if there are any....
