stunted growth?

I currently have 3 plants in my crop and the first was planted about 4 days before the first two and is a few inches taller than the rest. My main concern right now is that the 2nd one i planted has only split one time and the 3rd one has already split 3 and about to split the fourth time. What is the reasoning my 2nd plant isnt splitting?

if pictures are necessary please let me know

What do you mean by splitting? you have to remember that all plants will not grow at the exact same rate and speed. If you don't see any problems like nute burn, bugs and so on you should be all good....

post sum pics???

pictures help. and i wouldnt worry too much. ive had some start slower and end up twice as tall in the same time
