Another question about the transplant process. Do ...

At this stage, I would concentrate more on giving it a root enhancer rather than regular nutes although a LIGHT dose of nutes wouldn't be bad unless your soil already has nutrients in it... You need to give it some time to recover from the stress of the transplant. So this week, I'd water with just some root enhancers and then next week you can start the nutes... As for the topping, you don't want to do that right away either since that is also a very stressful technique and the plants are far too young... let them recover from the transplant first and then when they have 5 or 6 nodes, you can top. Red stems, btw, simply indicate stress and that is generally a nute stress or pH out of range... some purple strains will have naturally red stems so don't confuse the two. Good luck!
