I think you DID add your nutes a little early - but it's not catastrophic... and your instincts are spot on - just give her pH'd water (don't keep them contantly wet) for a while even after you transplant... they've been pretty stressed and transplanting will stress them even further so go gently! And never introduce nutes according to the chart they give you... it's not that they aren't telling you how to use their nutes in soil - it's that they're not weed-specific charts! Always start out at 1/4-1/2 strength and see how your plants react... if they take to it well, you can increase your dosage.
Good luck - I honestly think they'll be fine.
