Are my plants growing too slow?

Nice man, by the way, could it be that the slow growth has to do with the fact that I transferred the seedlings to the final pot when they were about 5 days old?

Yup

So when should one do the transplant?

Any type of root stress will temporarily slow growth, It is better to transplant when they are younger, I usually transplant a seedling right into a 5 gallon pot so I don't have to worry about it in the long run.
